Anybody know who might have produced these and what their value might be? They are about twice as thick as walnut grips. They have a Black border and backside. I am unsure of what the base material is (almost seems like some type of hardwood dyed black) The grips are nearly mint. I tried them on my Luger, They were a decent fit, but were strange feeling. I used to have a Desert Eagle and thats what it felt like. Someone with large hands would love these.
