This is a super cool and very rare M91/30 variety. The 91/30 was designated in 1930. This gun is dated 1928 which means it was previously converted from an existed M91. The Russians were already making some carbines out of longer rifles before deciding on the 91/30 spec. This gun also has a 2 digit SN. Very rare. I've been holding onto this one for years but time to let it go. Trades considered. Cash and carry. No shipping. I need to take a quick peek at your ID to make sure you're a FL resident. Thanks. Fair offers considered shoot me a number.
