I have an Iver Johnson's Arms & Cycle Works .32 with a serial number on the bottom of the trigger guard of 76182. All of the info I have found on the net keeps claiming the serial is found on the top of the barrel. Only the manufacturer's name is on the top of the barrel. On the handle bottom it reads PAT Aug 25, 96 and Pats Pending. Please provide me with info on this, value, age, etc. Thanks!!!!!
