Del, as I said earlier, I can't speak for the model C in particular, since it's a long time since I even saw one, and I can't visualize it. My "rationale" was a generalization, which applies to many grands -- "on most grand pianos, parallel to the line of the key-fronts and hence to the front of the front rail" If the keys are of reducing or increasing length, as on some Blüthners, Kaps etc. then the rule cannot be applied and an adjustment needs to be made to take into account the angle of the hammer rail to the front of the front rail. The main point is that the strike line is straight, I think you will agree, and that the treble end of it can be determined to within a fraction of a millimetre. If the keys are all the same length and if therefore the hammer rail is parallel to the front of the front rail, or the key-bottom, then my rule applies. If not, then other things have to be factored in but one way or another it doesn't require rocket science to determine where the strike line is meant to be. JD
