Hi John. Most of the older Pleyel pianos (from before 1870 or so) have the same "problem". You'd have to tweak with key height and hammer rest rail cloth to make sure every jack can get to it's rest position, and alow for a bit lost motion for the lower ones. But here you see that if you are really accurate in every other setting, that works quite well. Of course, the hammer rail must be perfectly straight and the buckskin of the noses very even, but on old Pleyel pianos, the hammer rail is kind of adjustable, I think for this purpose. Also I believe that those pianos had a bit more lost motion than none, and that the letoff was meant to be a bit further away from the strings, I suppose to allow for less precise adjustments. Ah, those skills are gone ! But that was the time that they "tuned" the hammer shanks to match the perfect thump for every hammer. Best regards.
