Duckhunter - nice 38 Single Action First Model you have there. Looks to be totally original and unmolested with original stocks and nickel finish. Baby Russians were manufactured from 1876 to 1877, with 25,548 made. Your serial number is close to the end of production, so likely made in 1877. Ship dates are more tricky with little available information on shipping dates, so the only way to get an official date is to request a factory letter from Roy Jinks.
