Since one of the administrators mentioned that things were a little 'stagnant' here, I thought I would show this. I recently acquired this WWII Colt that has a set of 'Sweetheart Grips' on it, along with the correct set of grips.
I have heard that during WWII some of the servicemen would get pieces of the canopies from downed aircraft and shape the plexiglass to fit their service pistols. After much cutting and filing and polishing, they would put a picture of their girlfriend or wife under the grip and mount it to the gun. Thus the name "Sweerheart Grips".
I have only seen a couple of other pictures of this before, but would invite others to show their's here.
