From a 1900 issue of "The Baker Gunner" courtesy of David Noreen
"We do not guarantee that every "B" (or "A") grade gun will be engraved from just the same design, but endeavor to have about the same amount of engraving on each. On receiving an order from a customer we try to select first, one which will fill the specifications as to gauge, weight, length of barrels, drop and length of stock, and then conform to customer's ideas as to engraving , as nearly as possible from guns we may have in stock, but always consider engraving of secondary importance. You may receive a "B" (or "A") with a different design of border, or a duck or a dog in place of the two quail or a dog pointing game, we cannot tell as it is our aim to give a variety of designs."
If the length of the choke constriction is > 1 1/2" - 2" the barrels could be factory. Note the left firing pin retaining screw has been replaced with a pin.
