I try to collect informations about this centerfire rim cartridge. It was used in the Galland Revolver and in a double barrel - Remington rolling block breech pistols. One type was made for the belgian police, the other for the russian army. The time frame is app. from 1870 to 1880.
The target is to find out what ammo survived in collections and what informations are available.
The left cartridge is made by Cartoucherie Belge Br
