This gun cannot be sold without a license. It is too new so you would not be able to just sell it to someone or to a pawn broker.

I'm not sure of the value of your shotgun. I have a Montgomery Wards Hercules, double barrel shotgun, with external hammers. With all the research I have done it is a Stevens 217. I have been looking for a set of barrels for this gun. Can you describe your gun to me. Petter
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. If it says "barrel and lug forged in one" (exactly the same except no "piece") it is by Iver Johnson Arms and Cycle Works.
It's really a Stevens model 94. Hercules was a Montgomery Ward brand name. Hercules was made by Iver Johnson from 1918-1943. I have a Montgomery Ward Hercules 16 ga. double. Does anyone know who made it. There are no brand or model numbers.SN X76777
