You may have received no response because of confusion over "original configuration". Do you mean to ask about the basic construction characteristics? If so, the first 110 was thinner (nominal 1/2 inch) than the current model. The steel rear spacer, between the two cast brass frame halves, also served as an integral spring which held the locking-bar in the locked position until actuated. The blade steel was 440C. Also, the ebony handle inlays were held in place with 2 1/16 inch pins and may have also been glued. The locking rocker bar pivoted on a brass rivet and the blade was stamped BUCK in a horizontal position along the spine of the blade. It seems the the very earliest models were stamped on the mark side and later on the pile side. The nail nick was a thin struck mark, rather than being deeply machined into the blade.
This first 110 was probably made in 1963 and various changes were made at fairly short intervals during the first two or three years. For more information, see Levine's Guide to Knives, edition 5.
