unidentified hand gun in question.?
I recently obtained a single shot that resembles a flashlight. I know it was used in the army and produced by a company called MB Associates around 1960. It has a PIN number on it, but I can not find anywhere you can connect your PIN number to know what is the weapon. Help? It seems that the largest caliber that you can enter is 357. I found it, Gyro-Jet U.S. Army MBAssociates Pen Flare gun.
I would consider that a gun show and find an expert. You may have something that is worth money.
