Ok, not a grail gun but a cool survivor with some police history.
One of my co-workers said he had an old gun that was locked up and his wife was going to throw it away and asked if I wanted it. Yes, please.
So, it's got a little coral reef growing on it, but other than that isn't in bad shape. I got it unlocked after ensuring it was empty. It was basically just goo'ed closed with whatever fungus was growing in its crevices. The grips are in great shape, the rust is only surface rust, and the barrel is surprisingly bright other than some goo at the end of the muzzle. it came with an old duty holster, too, although I don't know enough about it to know how old it is. It seems in too good a shape to be old enough, but it's certainly a design I've not seen before. I'll get some pictures of it and post up and maybe one of you old guys can explain it to me.
Anyway, I'm not sure what such an example of a Colt Police Positive .38 goes for, but it's certainly high in cool factor in my book.
