Nothing, nadda, zippo, zero no luck, a 24 oz dead blow hammer nothing. I think the wedge was driven in I can see on the right side of the frame the left hand side of the slot it looks like the metal has been peened out a little. I bent a 5/32" brass drift tapping on it with a small brass hammer.
Maybe I'll get one of those picture frame things and make this one a wall hanger.
