And operated as Iver Johnson Sporting Goods.
In 1883 the Iver Johnson's Arms and Cycle Works was formed and in 1891 they moved to Fitchburg, MA.
Looks like someone fired it a few times and didn't clean it very well, then threw it in a drawer for 100 years. Actually, even though the barrel is pitted you can still see plenty of plating in the bore. There is some pitting in the barrel but all of the plating is still intact in the chambers. Any idea how to get the rust off the bad parts of the finish so it looks more 'in the white' in these areas? Overall the gun doesn't look like it was fired very much. I guess IJs finish quality wasn't quite up to par with S&W or Colt, but then again they were only 1/3 of the price. The nickel plating at the muzzle literally peels away with my fingernail. There is another marking before the serial number but it is quite ways away.
I did take off the grips for the serial number (number is also under the topstrap when you remove the cylinder)
