Take a couple pictures of the other side, with emphasis on the side plate, so that we
can see how it fits into the frame, around its edges. Also, if you can, carefully remove
the grips, and take a picture of both sides of the grip frame, so that we can see
what is stamped there. Swing open the cylinder, and try to get a clear
picture of what is stamped on the flat area on the underside of the barrel, including
any letters stamped there. And finally, with the cylinder open, get a clear picture of
what is stamped on the rear face of the cylinder.
In the third picture of your second posting, there is a pin end very close to the top
portion of the grips. That pin-end looks to be flat, which raises a question about the
originality of the finish. These other pictures may help in judging the originality
of the finish.
