Awhile back, I added an M91 (with the old "arshin" rear sight) to my collection. I had thought it was Imperial Russian, as it is dated 1916 and has cyrillic lettering, but no typical Communist markings. I got to looking more closely last night, when cleaning it. It began to look less Russian. I checked the Mosin website this morning, and found that it is actually Serbian, made at the Sestroyetsk factory. Cool! It goes with my Yugo M48 and SKS, sort of. I seem to be getting a lot of weapons from that small corner of the world. Each has proven to be an excellent shooter in it's class. This Serbian Mosin out-shoots my Finn M39.
