Today's Puzzler

[Phil Bondi]

Hello all.

Actually, I know the answer to the puzzler..but I'm not sure of the 
remedy..so here goes.

-1915 M&H A (1st BIG clue)
-B2 is the first note in the tenor..clicking sound..sounds like a loose 
hammer head(not)..and it's not a loose upstop rail.
-2nd clue: it is not in the Hammers, Shanks, or Knuckles that I just 
replaced..nor is it in the regulation that was performed after replacing 
said parts.

That should narrow it down for you.

Be specific with your answer..and your remedy. My back will thank you 
for it.

Puzzlingly yours,

-Phil Bondi(Fl)
