Hello everyone, Im new to the forum here and I got something that really has left me stumped. I work for a local gun shop and a customer came in with this micro revolver. It appears to have been functional at one time but from what i gather its a single action single shot top brake design with a non-functional trigger. The cylinder is not intended to rotate. Maybe it shot blanks? No stamping on it anywhere and it appears to have a long horn bull carved on the grip. Any info please let me know, thanks.
