I would disagree with the post above that states that the 0 grade became the Ideal grade after 1913. I have seen that written before, but it doesn't make it any more correct.
I believe that a table that shows the comparison of pre and post 1913 guns should indicate that both the 0 and 00 grades were replaced by the field grade, and the Ideal grade would compare to the grade 1 guns, or based on the amount of engraving, to both the grade 1 and grade 2.
That was not to be Mr. Martin, JDW's above post is correct:
Grades were based on standard price points, NOT the amount or lack of engraving, or special order available options. With enough cash the factory would build you almost anything your heart desired in
any grade......
