Thanks for the info! Really would love to hear the stories this gun could tell....but then again, probably mostly closet or sock drawer stories...

The history end of things I think are very cool, almost pains me to keep it closed up.
Attached are a few more pics. I don't see any markings on the back of the holster. I do see a mark on the inside of the holster flap but it's worn from rubbing on the gun so I can't make it out... No tool, and honestly don't ever remember there being one when grandpa used to break the gun out to show me when I was a little tot.
