Points noted from D.L. Bullock.  I may not have been entirely clear
when I mentioned about piano wire gauge; I meant that apparently one
uses a _smaller_ wire gauge than the original, not bigger!  I also
agree with him that invariably one has to tune to much lower than
A=440, and often it is about A=435 or less.  Anyway, the barrel piano
I rewired worked and sounded fine after I used the same size wires.
