Top Left: French Mle (model) 1892 St. Etienne 8mm (erroneously called Lebel revolver by many) dated 1922.

Bottom: Russian Model 1895 Nagant 7.62x38R dated 1940 (Tula Arsenal)

Currently looking at some Swiss Model 1882s in 7.5mm Swiss (impossible to find ammo though)
If anyone is into this genre and has any suggestions on neat old military revolvers to collect, or has any to sell of trade, please let me know. When my 8mm ammo arrives (Nearly impossible to find these days) I'm taking all 3 to the range for some test firing.
