Most recently we found it on one of two Knabe 7' 8" (or something) grands we did back to back. They were built about two years apart. The first (and oldest) had an open-faced pinblock and normal nosebolts. The second had a closed in pinblock (obviously a rather crude modification of the original plate pattern) and two nosebolts with nowhere to go -- the location of the bellybraces had changed. Presumably a running design change in which plates intended for an earlier design were being used up. I have also encountered this feature in pianos that had been modified at the factory for various reproducer mechanisms. During the modification various bellybraces are either cut out or left out. Del
