It could be a Military and Police model that you have with that high a serial number,which was made from 1940-1945.I am not aware that it was made with a 2 inch barrel though.Does your serial number have a letter or number and letter before the serial number?If so please relist it,and I would have a better chance of identifying your Smith and Wesson revolver,along with when it was made.
