it was many years ago now when I realize that many interesting pics of unusual guns get lost when the auction ended

such threads especially about real rare guns becoming full of informations over the time if you take a look on all the facts you collect.
I remember the first time when I had a needle fire double gun in my hands. the owner had two questions - if I was abel to make ammo for this AND when was it made. first problem was possible and second was then impossible to say. with the information I got from old books and the complete stuff here in this thread I am able now to tell which year such a needle fire gun was made.
