Thanks for the info guys! Yes it is a swing out cylinder and not a top-break. Serial number under the butt is also seen under the barrel and is covered by the hand ejector when it is closed. No markings at the rear face of the cylinder. If you ask me, it looks more like model 10 but is in 32 long. On the top side of the barrel is the patent dates, on the left (if you are holding it and the barrel facing outwards) is the "smith & wesson" marking and on the right is the .32 S&W long ctg. So guys, any more info? Can't find my bluetooth device to upload the pics.
