I have one marked nickel steel. Flaming bomb. Length matches my original model 12 Riot. Pretty sure it has been reblued. Local "expert" thinks it is from the '20's Really nice shape. Bore is mint. Barrel markings are sharp but serial # is faint. Want to list it here before I put it on GB but no idea what to ask. I am thinking $250-$350 but I may be way off base on this one.
