Hello! I'm hoping someone could help me with my curiosity about a stamp. Recently the grips were removed from this old revolver and there was an odd star stamp on the butt by the number. From doing a search it sounds like it indicates the gun had been sent back for repair. The gun has been lettered but there's no mention of a repair being done. Not sure if that part was just missed or if the star may indicate something else. I'm mainly curious about this so any thoughts? Thanks in advance!
