Mint Condition Schenkl Percussion Fuse
You can't upgrade this example! Absolutely top shelf, the cap is marked "J.P. SCHENKL / PAT. OCT. 10, 1861" and the stamp is crisp and clear. The anvil cap is frozen in the firing position. The safety screw is intact. It's purpose was to prevent the slider from shifting during the transportation, casuing a premature explosion of the shell. The Schenkl shell with the percussion fuse was considered the most reliable projectile in the Federal arsenal.
