<HTML><HTML>Greetings,            Yagat me! Possi= bly, there was a particular sonata or some piece that someone played and it = employed the use of  those notes...and they practiced the piece till th= ey broke...on all three pianos; but that playing would have had to been awfu= lly forceful!           I think the Hmilton with th= e broken strings had its hammers broken/mangled there as well, so the last t= ech took the hammers out of the one Hamilton and put them in there, leaving = the first piano with NO hammers. Then maybe he took mangled hammers from the= stringless one and put them in the third (Kimball) I dont know...this is like on of those math teaser puzzles. Julia Reading, PA</HTML>
