Good eye, Sharps! I wouldn't know French Amber flint from Lithuanian Bronze flint, so I haven't a clue...No sir, I'm sorry I can't tell which country either. However, you are most correct, that is a cool old pistol!!!
Tell ya what, I just noticed something which might be meaningless. It has a French Amber flint in the jaws. Flints aren't permanent so....but I'm thinking it might be French.
