The Baker Gun & Forging Co.'s first entry into the low priced field was their box lock Batavia Hammerless --
which was for a time listed as the C-Grade. A lot of these box lock Bakers/Batavias were marked New Era --
and sold by The Fair in Chicago. These guns resemble Syracuse Arms Co. doubles because Frank A. Hollenbeck was the Superintendant of Baker Gun & Forging Co. 1889 to 1893, when he left to form Syracuse Arms Co. But, they have the narrower Baker barrel lug, not the 5/8 inch wide lug of Frank's Syracuse Arms Co., Baltimore Arms Co, and Hollenbeck/Three-Barrel/Royal Gun Co. firearms.
Just to muddy the waters, there was a much later Baker boxlock with the bolting of the later Paragons and above --
None of the Baker or H & D Folsom paper in my collection of old catalogues shows this gun.
