It is a fairly late Iver Johnson 16-gauge ejector double, certainly not a Super-Trap!! At some point during the 1930s they quit color case hardening the receivers and went to the black gun metal finish. By 1937 they had dropped the Hercules name for it from their catalogs. The patent dates on the watertable are for William O. Barnes Patent No. 1,131,984 and Patent No. 1,137,045. From the 1937 Iver Johnson catalog --
