let off gone berzerk

[Marcel Carey]

Joseph,
 
My guess is that the letoff rail came loose from it's retaining screw
and the hole bar moved for that section. Before you start regulating the
letoff, just make sure that the whole bar is well secured in their
respective brackets.

OK, customer says no power in last octave plus on her run-of-the-mill
Wurlitzer console. I look at hammer blow and it is at 1 3/4". Let off is
at 1 1/2".   Yikes, I say! The rest of the keys all let off around 1/8".
Piano just was moved, but under supervision of owner. No visible signs
of damage anywhere. 
 
Question: How did the last octave plus get in this condition, which
customer swears is a new problem since move? I'm stumped. I don't want
to do the adjustment to let off with out understanding the problem of
how it got so far off in this one area. Should I be looking for
something a whole lot more hidden?
