Stallones, oddly I had a Wm, Moore with a side lever. If I remember correctly it gave an address on the top rib as Oxford Street, London which was never a true Wm. Moore address; clearly a forgery. It had Birmingham proof marks, which may also have been forged. I de-activated it to proof house standards so that it could be sold as a wall piece. This particular gun was of very poor quality and not safe for use. A lot of the better known Gunmakers in Britain had their works forged. Sometimes if not sure they need to be looked at by an expert on the Maker.

Not saying that there was anything wrong with your Moore; I have a little beauty by him in 20 bore. But that Manton above doesn't look to me as being right somehow. Lagopus.....
