Ron,
Thank you. Maybe the guy was just real nervous and whittled away at it.

My grandfather was in the trenches in France in WW I and to pass time, he collected all the aluminum foil wrappers from chewing gum. In those days, the wrapping was solid aluminum foil. He packed them into a softball size ball and to this day, my brother now has it. He said it was just something he did to pass time when it was quiet and couldn't leave it behind when he came home. If this gun saw any action, who knows what happened. I'll give it a closer inspection when I get it.
Thank you!
Steve
