Iver Johnson is most often associated with the HERCULES trade name. sales@countrygunsmith.net *If that statement marked on the gun actually says "barrel and lug forged in one piece" it is a Stevens.

Yes, I have a 12 gauge choke bore barrel & lug forged in one by Iver Johnsons Arms & Cycle Works. Champion is clearly listed on the shotgun and it was manufactured in Fitchburg, MASS USA.
Diamond Arms was a trade name used by Shapleigh Hardware Co of St Louis from the late 1800s to about 1950. The guns were made by G. B. Crandall, Harrington & Richardson, Hopkins & Allen Arms, J. Stevens Arms Co, and probably a few others. A 410 single shot is most likely a Stevens product. If that statement about one piece barrel actually says "barrel and lug forged in one piece" it is a Stevens. If it says "barrel and lug forged in one" (exactly the same except no "piece") it is by Iver Johnson Arms and Cycle Works.

The value of a IV FR Johnsons arms 32 caliber Fitchburg mass revolver is actually dependent upon a number of factors. Most important of these factors would be the condition of the revolver.

it was made in 1918
