OK; here are my three Stevens guns, the first doubles I ever owned. I sometimes still think I shoot them better'n any of 'em! They're all stamped 5100, which Researcher has said is actually an action shape designation (or something like that) and not a model number, but a lot of folks refer to them as 5100's. They all have real checkered walnut wood and twin ivory beads. Only one fully owns up to being a Stevens; the 16ga is marked Springfield and the 20ga is marked Ranger.
16 gauge...
20gauge...
and .410, which some folks list right up there with the Winchester 24 as the ugliest double ever made. I like it though...
