Check with the guys at smith & wesson forums. You have what looks like a K200. Serial # will verify year. Made by Smith for the Brits back during the war in 38/200 or 38 S&W with a 200 gr bullet. After the war, the war dept sold these off and they were converted (some not very well) by numerous companies in the UK for sale back in the States (you could buy them mail order for $19.50). Some of the conversions are ok some are not very well done and in most cases it is advised to have a gunsmith look it over.
