Hmmmmmm, I don't often get to look at real early hammerless Bakers like this one. I look at where the firing pin screw is at and it is at the lower position like you see on the later Bakers made by Folsum. Gordon, for some reason Baker seemed to use the dogs, birds at will, regardless of "A" or "B" grade. It does seem as if they use the engraving pattern is blocks or in lots.
