Dating from around 1894 and used in the revolver from A. Spirlet & Cie., Liege, Belgium. The Spirlet revolvers were based on the Galand system, however they used a top break design with a star extractor that put them way ahead of their time. (Erlmeier, Brandt Ref....

Relatively modern (1970’s in all probability) cartridge based on an old design for the Galand reloadable cases where the bullet is screwed into the case on reloading and upon firing the thread is stripped away from the bullet. The 12mm Serpette was made by a...

This cartridge resembles the 450 Short CF Revolver. Erlmeier, Brandt does not offer a lot of info on this except that it was the largest of the Montenegrin cartridges. (Erlmeier, Brandt Ref. 169).
