Drew, On page 3 of the 1909 Baker Gunner, they indicate that:
"The first model Baker Hammerless was built in two grades designated as the "A" and "B", the difference consisting chiefly in the barrels of which the "A" had fine Damascus, the "B" London twist.
These guns have given splendid satisfaction down to the present time, but for the sake of later models and higher finish, the "A" grade is being gradually closed out and the "B" grade is manufactured only in limited quantities."
As has been previously mentioned, thanks very much for all your efforts with the Paper Trail.
