I have a Charles Smith 12 bore 30" Damascus top lever hammer ejector gun with nitro proofs. It has profuse scroll enrgaving and a solid action body. It dates from the 1880s and the Southgate style ejectors were added some time later, I presume. Quite a nice gun. Smith traded from atleast 2 addresses in Marketplace, Newark-on-Trent. Mine is marked #37 Marketplace. Sorry I do not know how to post a photo of it.
