A friend of mine said he wanted to show me "his grandpa's old Army pistol", and pulled out a WWI vintage Colt M1911 in outstanding condition, although it had rubber target grips on it. He didn't know what it really was, so I filled him in and helped date it by s/n. I mentioned it was a shame it didn't have the original walnut stocks, and then he reached back in the drawer and said "these things?" Sure enough.

I'd consider that pistol to be priceless!
