Not sure what you mean by a "12 barrel." If it is a 12 inch long barrel, it has been cut off and is an illegal firearm. In any case, .410 single-shot Stevens guns bring $100 in top condition. sales@countrygunsmith.net
These single-shot guns dont bring much money, but the magnum with 36" barrel will bring somewhat more than a typical 94F. Figure $75-$125. www.countrygunsmith.net I Bought one today and paid $125. Not worth much money but is a good looking old gun. Couldnt pass it up.
