I have recently obtained a, what I believe to be, old S&W 38 caliber top-break hammerless pistol and am attempting to find any information I can on it. To date I know it is very probably a version #4, or model 4, of this type pistol referred to as a "safety hammerless" pocket pistol. I have checked the serial number both on the butt of the pistol and the face of the cylinder and they match. Can anyone out there either give me some more info on this or at least point me in the right direction of determine age and place of manufacture?
