    I have one of these Revolvers as shown in the Flayderman's book. It has the 79/83 Patent dates and Iver Johnson & Co Makers Worcester Mass USA roll stamp on the barrel. I live in NH and purchased the revolver just over the border in Maine (I am a FFL Dealer) so It didn't get far from Worcester. The trigger spring on this one is broken so it only functions in Double Action. The Grips have Dogs Heads on them and the LH grip is broken. Flayderman's also said these were 6 shooters and mine is a 5 shot. I first thought it was a 38 S&W but when I put a round in the cylinder it had room to wiggle around they also wrote that they were 32/38/41/44 calibers but my 10MM and 41 Mag rounds would not fit, so unsure of caliber. There is a 57 stamped on the frame and 249 on the extractor and cylinder.

    Pictures sure would be of some assistance to the experts who can probably identify it for you.

    The .41 of the day was .386", falling between a .38 (.357) and present day .41.

    The best bet is to check cylinder diameter with micrometer. 38 (.360) 41 (.412) 44 (.432) give or take a thousandth. Most of those are S&W calibers make sure to use the right type of ammo .
