Sierra embedded blanks with WWII North American Aviation P-51 Mustang aluminum wing material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II and the Korean War, among other conflicts. The Mustang was designed in April 1940 by a design team headed by James Kindelberger of North American Aviation in response to a requirement of the British Purchasing Commission. The Purchasing Commission approached North American Aviation to build Curtiss P-40 fighters, but North American Aviation proposed the design and production of a more modern fighter. The prototype NA-73X airframe was rolled out on 9 September 1940, 102 days after the contract was signed.

The definitive version, the P-51D, was powered by the Packard V-1650-7, a license-built version of the two-speed two-stage-supercharged Merlin 66 and was armed with six .50 caliber AN/M2 Browning machine guns. P-51s were used by the USAAF's Eighth Air Force to escort bombers in raids over Germany. The RAF's Second Tactical Air Force and the USAAF's Ninth Air Force used the Merlin-powered Mustangs as fighter-bombers to ensure Allied air superiority in 1944.

The P-51 was also used by Allied air forces in the North African, Mediterranean, Italian and Pacific theaters. During World War II, Mustang pilots claimed to have destroyed 4,950 enemy aircraft.

During the Korean War, the Mustang had been redesignated F-51. It was the main fighter of the United States until jet fighters like North American's F-86 took over this role. The Mustang then became a specialized fighter-bomber. Despite the advent of jet fighters, the Mustang remained in service with some air forces until the early 1980s. After the Korean War, Mustangs became popular civilian warbirds and air racing aircraft.

These blanks are made using original aluminum from USAAF P-51D Mustang, serial number 44-14379. This P-51D 'Little Doc' was engaged in aerial combat with four German Me 262 jet fighters on April 5, 1945. After damaging one 262, Lt. Cowley in 'Little Doc' was hit, and Cowley bailed out. Though wounded, Cowley landed safely in Belgium and returned to his unit. This aircraft was excavated in 2006. The material is certified and distributed by Hardin Penworks, LLC. This material is guaranteed to be 100% Authentic.

Sierra and Bolt embedded blanks with WWII North American B-25 Mitchell aluminum wing material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The North American B-25 Mitchell is an American medium bomber that was introduced in 1941 and named in honor of Major General William "Billy" Mitchell, a pioneer of U.S. military aviation. Used by many Allied air forces, the B-25 served in every theater of World War II, and after the war ended, many remained in service, operating across four decades. Produced in numerous variants, nearly 10,000 B-25s were built. These included several limited models such as the F-10 reconnaissance aircraft, the AT-24 crew trainers, and the United States Marine Corps' PBJ-1 patrol bomber.

Sierra embedded blanks with North American T-28C Trojan material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The North American T-28C Trojan, a piston-engine military trainer, was a cornerstone of U.S. Navy pilot training in the post-World War II era. First flown in 1949 and entering service in 1950, it was designed to replace the T-6 Texan. Powered by a Wright R-1820-86 Cyclone engine producing 1,425 horsepower, the Trojan reached speeds of 343 mph and had a range of 1,060 miles. The T-28C variant, built for the Navy, featured a tailhook, shorter propeller, and reinforced structure for carrier landings, making it ideal for advanced training. Nearly 2,000 T-28s were produced, including 299 C models, training pilots in aerobatics, gunnery, and carrier operations. During the Vietnam War, some Trojans served in counter-insurgency roles. Its predictable handling and excellent visibility earned it the nickname “Pilot Maker.”

These pen blanks are crafted from the authentic fuselage skin of T-28C Trojan, Bureau Number 140597, preserving its legacy. Ideal for aviation enthusiasts, veterans, or collectors, they transform this trainer’s history into a unique writing instrument.

Bureau Number 140597 History: Accepted by the Navy in December 1956, BuNo 140597 served primarily with Training Squadrons Two (VT-2) and Three (VT-3) at NAS Whiting Field, Florida. In 1968, VT-3 set a record with 174 instructors and 162 T-28s, flying 110,000 instructional hours. Retired to the Military Aircraft Storage and Disposition Center in 1975, it was sold in 1982.

Sierra embedded blanks with Northrop B-2 Spirit metal material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The Northrop B-2 Spirit, commonly known as the Stealth Bomber, is a cornerstone of U.S. Air Force strategic capabilities. Introduced in 1997, this subsonic, flying-wing aircraft was designed for stealth, enabling it to penetrate advanced air defenses undetected. Powered by four General Electric F118-GE-100 engines, each producing 17,300 pounds of thrust, the B-2 can carry up to 40,000 pounds of ordnance, including nuclear and conventional weapons. Its range exceeds 6,000 nautical miles without refueling, extendable with aerial refueling, making it a global strike platform.

The B-2’s stealth is achieved through its low-observable design, radar-absorbent materials, and advanced heat signature management. A notable component is the titanium upper engine exhaust shield, which mitigates the heat signature of the F118 engines. For instance, a section of titanium from such a shield, replaced due to in-flight cracking, highlights the material’s critical role in thermal stealth. This panel was later redesigned to enhance durability, reflecting ongoing improvements in B-2 maintenance.

With only 21 units built, each costing approximately $2.1 billion, the B-2 remains one of the most expensive aircraft ever produced. Operated by the 509th Bomb Wing at Whiteman Air Force Base, Missouri, it has seen combat in conflicts like Kosovo, Iraq, and Afghanistan, delivering precise, high-impact strikes.

These titanium embedded blanks are crafted from a Northrop B-2 Spirit’s upper engine exhaust shield, replaced due to structural cracking. The material is certified and distributed by Hardin Penworks, LLC, and is guaranteed to be 100% authentic.

Pre-tubed embedded blanks with Northrop P-61B Black Widow material.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The Northrop P-61 Black Widow is a twin-engine United States Army Air Forces fighter aircraft of World War II. It was the first operational U.S. warplane designed as a night fighter.

Named for the North American spider Latrodectus mactans, it was an all-metal, twin-engine, twin-boom design armed with four forward-firing 20 mm (.79 in) Hispano M2 autocannon in the lower fuselage, and four .50 in (12.7 mm) M2 Browning machine guns in a dorsal gun turret. Developed during the war, the first test flight was made on 26 May 1942, with the first production aircraft rolling off the assembly line in October 1943.

Although not produced in the large numbers of its contemporaries, the Black Widow was operated effectively as a night fighter by United States Army Air Forces squadrons in the European Theater, Pacific Theater, China Burma India Theater, and Mediterranean Theater during World War II. It replaced earlier British-designed night-fighter aircraft that had been updated to incorporate radar when it became available. After the war, the P-61 was redesignated as the F-61, and served in the United States Air Force as a long-range, all-weather, day/night interceptor for Air Defense Command until 1948, and for the Fifth Air Force until 1950. The last aircraft was retired from government service in 1954.

On the night of 14 August 1945, a P-61B of the 548th Night Fighter Squadron named Lady in the Dark was unofficially credited with the last Allied air victory before VJ Day. The P-61 was also modified to create the F-15 Reporter photo-reconnaissance aircraft for the United States Army Air Forces and subsequently the United States Air Force.

The Oakland–Alameda County Coliseum, or Oakland Coliseum for short, is a multi-purpose stadium in Oakland, California, United States, which is home to the Oakland Athletics of Major League Baseball (MLB). The stadium opened in 1966 and was the last remaining stadium in the United States shared by professional football and baseball teams having done so from 1968 until 2019. From 1966 until 1981 and again from 1995 until 2019, the stadium was home of the Oakland Raiders of the National Football League. It was also the home of the Oakland Invaders of the United States Football League from 1983 to 1985. The Coliseum was also home to some games of the San Jose Earthquakes of Major League Soccer in 2008–2009 and hosted games of the 2009 CONCACAF Gold Cup. The Oakland–Alameda County Coliseum complex consists of the stadium and the neighboring Oakland Arena.

The Coliseum has 6,300 club seats, 2,700 of which are available for Athletics games, 143 luxury suites, 125 of which are available for Athletics games, and a variable seating capacity of 46,867 (or 55,945 without tarps) for baseball and 63,132 for soccer. It has a seating capacity of 56,057 for football as of 2019. In seating capacity, Oakland Coliseum is the eighth-largest MLB stadium.

While an NFL venue, the stadium was the second-smallest NFL stadium, larger only than Dignity Health Sports Park, the temporary home of the Los Angeles Chargers.

On April 3, 2017, Opening Day, the Athletics dedicated the Coliseum's playing surface as Rickey Henderson Field in honor of MLB Hall of Famer and former Athletic Rickey Henderson.

Ohio Stadium, also known as the Horseshoe, the Shoe, and the House That Harley Built, is an American football stadium in Columbus, Ohio, on the campus of The Ohio State University. Its primary purpose is the home venue of the Ohio State Buckeyes football team; it also serves as the site for the university's Spring Commencement ceremonies each May.

From 1996 to 1998, Ohio Stadium was the home venue for the Columbus Crew of Major League Soccer prior to the opening of Columbus Crew Stadium in 1999. The stadium also was the home venue for the OSU track and field teams from 1923-2001. In addition to athletics, Ohio Stadium is also a concert venue, with U2, Taylor Swift, The Rolling Stones, Pink Floyd, and Metallica among the many acts to have played at the venue.

The stadium opened in 1922 as a replacement for Ohio Field and had a seating capacity of 66,210. In 1923, a cinder running track was added that was later upgraded to an all-weather track. Seating capacity gradually increased over the years and reached a total of 91,470 possible spectators in 1991. Beginning in 2000, the stadium was renovated and expanded in several phases, removing the track and adding additional seating, which raised the capacity to 101,568 by 2001 and to 102,329 in 2007. In 2014, additional seating was added in the end zone, raising the official capacity to 104,944. Another renovation to add more luxury suites began in 2017 and will eventually lead to a decrease of 2,600 seats. It is the largest stadium by capacity in the state of Ohio, and the third largest on-campus football stadium in the United States. Ohio Stadium was added to the National Register of Historic Places by the National Park Service on March 22, 1974.

Oldsmobile was a brand of American automobiles produced for most of its existence by General Motors. Originally established as "Olds Motor Vehicle Company" by Ransom E. Olds in 1897, it produced over 35 million vehicles, including at least 14 million built at its Lansing, Michigan factory alone. During its time as a division of General Motors, Oldsmobile slotted into the middle of GM's five divisions above Chevrolet, and Pontiac, but below Buick, and Cadillac, and was noted for its groundbreaking technology and designs.

Over 1 million Oldsmobiles were sold annually 1983-1986 but by the 1990s, the division was facing growing competition from premium import brands and sales declined. When shut down in 2004, Oldsmobile was the oldest surviving American automobile marque, and one of the oldest in the world, after Mercedes-Benz, Peugeot, Skoda, and Tatra.

In the 1930s, Oldsmobile produced two body styles of automobile, the 6-cylinder Series F and the longer 8-cylinder Series L. Wooden artillery style wheels were standard features, but the wire wheels were optional equipment at the time of the original purchase.

The early 1930's was a difficult time for automobile manufacturers due to the Great Depression. The Oldsmobile F-31 was a suitable option for many due to its relatively low sticker price and additional rumble seat which could carry luggage or additional passengers.

These blanks are made from the hickory wooden wheel spokes of a 1931 Oldsmobile Model 30 F-31. The wood is certified and distributed by Hardin Penworks, LLC. This material is guaranteed to be 100% Authentic.

Osage Orange Pen Blanks – 5" × ¾" Square

Scientific Name: Maclura pomifera
Common Names: Osage Orange, Hedge Apple, Bodark, Horse Apple

Origin

Osage Orange is native to the south-central United States, primarily found in the Red River Valley region of Texas, Oklahoma, and Arkansas. It was historically planted widely as living fences and windbreaks across the Midwest and eastern U.S. The finest turning stock today is typically sourced from mature trees in Oklahoma, Texas, and surrounding states.

Description & Characteristics

Osage Orange is one of the most striking and durable woods available to pen turners. Freshly cut heartwood ranges from bright golden yellow to vivid orange, often darkening to a rich amber or golden brown with age and exposure to light. It is extremely dense and heavy with a tight, interlocked grain that gives finished pens a bold, warm glow.

These premium 5" × ¾" square pen blanks are pre-squared, kiln-dried, and carefully selected for color and density, making them ideal for turning into eye-catching single-barrel or slimline pens that develop beautiful character over time.

Turning Tips for Osage Orange

• Extreme Density: Very heavy and hard (Janka hardness around 2,040 lbf). It turns slower than softer woods but rewards patience with crisp, clean results.
• Tools & Technique: Sharp carbide tools are recommended for best performance and minimal tear-out. Take light cuts at moderate lathe speeds.
• Color Stability: The vibrant orange color will darken naturally over time when exposed to light — many turners love this aging character.
• Sanding & Finishing: Sands smoothly and takes CA glue, friction polish, shellac, or most pen finishes beautifully, producing a deep, lustrous shine.
• Dust & Safety: Produces fine, bright yellow dust — always use strong dust extraction and wear a good respirator. Many turners note a pleasant, mild citrus-like scent while turning.

Perfect for pen turners who want bold color, exceptional durability, and a unique look that improves with age. Osage Orange creates pens with a warm, vibrant personality that stands out in any collection.
