I picked up a model 13-2 today in a pawn shop. It is a round butt 3" bbl. blued gun. I had never seen one of these before, and it made a very neat revolver. The serial no. is 8D73348. Can anyone tell me when it was made ? It is pinned and recessed also. It had a set of ivory looking grips on it , but I don't believe they are real ivory. Is there a way to tell real ivory from fake. They look for all the world like the real stuff, but I find it hard to believe that they are real. On the inside they are stamped "Alexander's Guns, Inc." and an address of 2327 San Jacinto, Houston Texas . The gun is in excellent condition, and I got it so cheaply that it doesn't matter value wise. I am just curious. I would post pics, but I don't know how. Thanks for any help.
