Richard, I am sorry, but I do not understand your post. With (older) hand-built pianos, all of this forefinishing stuff was accomplished in reference to to: - String height, measured from the keybed to the under-side of the vbar, usually at several points; and, - Strike point, determined by (among other things): 1.- What I would characterize as the "raw" tone of an unshaped, unvoiced new hammer; and, 2.- What I would characterize as "experience influenced geometry. That is to say, the action was not fit to the keybed until the (relatively) stationary parts were in place (and tied down). Since this was the case, "line up pins" were (are) not only superfluous, but contraindicated, as they tend to give impression of their being only one "correct" location. So, while in the case of some pianos, finding one that is "right" may be of some value. In the case of an M, however, the numbers (and, therefore, relative "rightness") of one piano may be disasterous on another. Someone else has probably already spoken to this. Best.
