I just aquired a S&W 32-20 revolver that dates between 1902 and 1905 according to SN. I called S&W they said the dates above are accurate. The gun appears in good condition externally but has some (Flash Burning) on the frame between the barrel and cylinder. I was advised not to fire the gun by a gun smith and by S&W. I have serveral boxes of old ammo for this gun. Any one out there have an idea what it's collector value may be?
