Recently acquired are these 7.65 x 54 Mauser dummy cartridges. The two on the left were made by Winchester and are headstamped BELG. 7.65 M/M . The third from left is headstamped E P 99 (the 99 is “almost” missing a 9 but I am fairly certain it is correct). The cartridge on the right is headstamped REM-UMC 7.65 m/m All have a hardened gutta percha type material in the primer pocket. The E P (Ecole Pyrotechnique) cartridge was originally a Belgian case which I assume was made into a dummy in Belgium. I assume the U.S. made cases were sent to Belgium as loaded cartridges and made into dummies there. Additions ? Corrections ?
