17" Antique Style Civil War Bowie Knife For Sale

I am listing this as a reproduction because I am fairly certain that's what it is.
The blade appears to be made on a grinding wheel, and the stag handle is original. An old-type nail is punched into the end of the handle. (Look at pics). Overall, this is a really nice Bowie knife I believe is very old, perhaps late 1800s/early 1900s, but someone punched those letters into it to try to increase its value.its marked

Analyzing the Mark vs. Historical AuthenticityWhile the stamp is highly compelling, it raises significant red flags when compared to authenticated Civil War records. There is a very high probability that this piece is a twentieth-century fantasy piece or reproduction rather than a genuine Confederate weapon manufactured during the war.

• The Wording Anachronism: The inclusion of "C.S.A." (Confederate States of America) directly stamped into a factory maker's mark is highly uncharacteristic of authentic period weapons. Genuine, wartime Boyle & Gamble (B&G) blades were marked for business purposes using "BOYLE & GAMBLE / RICHMOND, VA". They did not stamp "C.S.A." onto the ricasso in this manner; that acronym was predominantly popularized on postwar memorabilia, replicas, and fantasy items produced in the mid-to-late 20th century.
• The "B & G" Separation: On authentic pieces, the initials were rarely stamped as a standalone block detached from the main manufacturer name.
• The Antler Crown Handle Context: As noted previously, genuine Boyle & Gamble Bowie knives almost exclusively utilized walnut wood slabs or sometimes cast brass hilt configurations. Finding a crown stag handle paired with a raw "C.S.A." ricasso block stamp is a hallmark combination often seen in mid-to-late 20th-century vintage replica Bowies sold to collectors.
• Artificial Aging: The pitting and patina around the lettering appear somewhat uniform, giving this example a dug appearance.

SummaryThe knife is a great-looking, rugged vintage Bowie knife with excellent eye appeal, but the specific layout of the "RICHMOND VA C.S.A. / B & G" stamp strongly suggests it is a reproduction intended to mimic a Confederate artifact.
