OK, this is a long, long shot but I have a pair of these in my "treasures" and have no idea where I got them. I don't want to split them up and both are in good shape with no breaks, cracks or repairs. I took several pictures that will hopefully answer any questions you have. One has a Walther plate and the other appears to be horn. $425 shipped for the pair and payment by check of any kind.
