Sweetheart Grips

[cdmech]

I just bought this sweetheart grip on Ebay. I'm really impressed by how well it was carved, and just couldn't resist trying it on my Luger! Recently I fitted new wood grips, and even with the help of a Dremel it was very time consuming. How someone hand carved these two pieces of plexiglass to fit so well and hold the picture amazes me.
Unfortunately the seller didn't have any history with it, but if taken at face value, it sure has been around.
I would appreciate any thoughts or opinions on it, and would like to see pictures of any similar grips.
Thanks,
Marc
