I recently acquired this Smith and Wesson and ejector revolver. It appears to be model 1899 first model but I’m not a hundred percent sure. Serial number stamped under the barrel, on the cylinder and on the frame at the bottom of the butt is less than 800. It says 32 Winchester CTG on the barrel. It has adjustable sights and a 5 inch barrel. It has black hard rubber grips and a round butt. The inside surface of the crane and the opposing frame surface have the stamping 4663. It is missing the ejector. The rod and spring are there but I need the star shaped part. I also need to determine the exact caliber and proper ammunition for this firearm.
