I am posting in the Winchester rifle section since there is no pistol catagory.. 🙂 This gun was given to a friends father some 40 years ago by a guy who had a matched pair of them in some kind of ornate boxed case…It obviously started life as a rifle and I am not suggesting it came from the Winchester factory…It is however of very skilled hands in its transformation to a pistol..I post this on the off hand chance that whoever did this may have produced others..So While I know its a long shot at best. maybe someone may have heard of others of its Ilk, or the co. or single gunsmith responsible for it…I know most collectors will consider an ab oration..but it is interesting and if someone could shed a ray of light on its origins then this post was worthwhile…..As a side note I have not seen the gun personally, but am assured the workmanship is superb…[Engraving not withstanding], which appears to have been added later…. also, He has shot the gun and said that it was a handfull but doable…A 45-70 is a lot of pistol!
