Found an old one
I friend of mine found an revolver hidden in the barn on the farm that his family has owned for 55 years It was wrapped in a rag and stuffed between some beams.There is a "release" in back of the trigger ,when it is pushed you can move trigger to firing position. There is no trigger guard or serial number.On the frame in front of the cylinder is an oval.In it are the letters GM and the outline of a horse.Front of frame has the number 3 on it. Grips seem to be plastic.It loads thru a gate on right sideand is .32 cal. Any Ideas???
