I read there are a few Iver Johnson experts on this forum. I have just inherited my Dad's Iver Johnson hammerless .32., The top of the barrel is stamped, Manufactured in Fitchburg, MA, Pat Apr 6(?)86, Feb 15 87, May 10 87, Mar 13 88, Aug 25 96, Pat Pending. I cannot find the serial number. Any thoughts on where it might be? It is not on the frame nor under the trigger guard. The pistol is not is good shape. A lot of the nickel is worn off. This is not a working pistol and I understand it does not have a extrinsic value. Any info would be appreciated.
