The 45-70 cartridge was the official military of the US from 1877 to 1898 manufactured by Frankfort Arsenal, United States Cartridge Co, Union Metallic Cartridge Co., Winchester, and E. Remington and more recently heads tamped by Peters, Remington, Lyman, Hornady, Federal, and others.
Surplus Springfield rifles and Gatling guns were used around the world so I wonder about cartridge production. 45-70 cartridges were manufactured in various countries but which ones especially before 1900?
I have head stamped rounds from Eley and Kynoch of England, George Roth of Austria, SFM of France, China contract by Winchester and China, Dominion of Canada,
How about Mexico, Spain, Russia, Czech, Argentina, middle East, or Germany??
