I'm sure this will be an easy one for firearms enthusiasts, but it's not my area I'm afraid .
Could anyone please identify the type, date, country, etc of this weapon. (I'm guessing 1857 ish?) The junkshop I bought it from knew nothing just describing it as a wallgun for decorators.There is a number on the stock - see photo. The mechanism is in full working order, and the ramrod can (now) be withdrawn. Thanks very much for any help
