Gunny:
I can't tell you where the Baker box-lock guns fit into a specific Baker gun manufacturing period; but there are numbers of outward cosmetic and mechanical differences between the Baker and Syracuse Arms Company box-lock models. The most obvious differences are that the Baker gun will have three exposed pins (not screws) on each side of the frame, while the Syracuse/Hollenbeck gun will have only two exposed pins on either side of the frame; the second most obvious difference is the barrel lug, 3/8" wide on the Baker and 5/8" on the Syracuse (the Baker lug is also longer). Other cosmetic differences include rib matting, safety sides, trigger plates, butt-plates, etc; etc.
