I have a Smith&Wesson 25-2 in 45acp #N3381xx that has a 6.5" tapered slim barrel marked "45 CAL. MODEL 1950" and the bluing on the barrel does not quite match the rest of the gun, it's more of a plum color. The gun does not apear to be re-finnished and the color differance is not huge but it's there. I bought the gun for a good deal because the dealer(and I) thought it was a put together parts gun, but it's in really nice shape and I read on this forum awhile ago that S&W sold some model 25's with 1950 barrels factory. but I can't find that information. I have also heard that some S&W revolvers had the bluing on the barrels turn a plum color with age when the frames did not. So..... does anyone know the facts or do I indeed have a re-barreled gun?
