Z4972 .50 Crispin Long Rimfire Cartridge (Patent No. 49,237 of 1865)

Description: Very nice example of a patent ignition .50 Crisping long rimfire cartridge. This cartridge was invented by Silas Crispin who was awarded a patent for an improvement on priming metallic cartridges on August 8, 1865. This cartridge is still classified as a rimfire although it doesn't mirror your typical rimfire cartridge. The wide rim in the middle of the case held the fulminate. This .50 example was used in conjunction with the modified Smith carbines. Nice example with 6 vertical crimp marks around the case mouth.

Headstamp: None

Measures: OAL 1.974" CL 1.530"
