Challenge question: Where's the Squeek?

[Nancy McMillan]

Roger quized us:

> This was on my own piano, a 1913 Steinway model O, as yet not rebuilt, a
> soft but audible squeeky sustaining pedal, Steinway O, 1913, all original
> stuff.
> 
> The squeek was pitched at C5, occured on the depression of the sustaining
> pedal, was not in the pedals or lyre mechanism, could be reproduced by
> pushing up on the damper tray.  
> 
> It took me 45 minutes to find it, very exasperating, but in 23 years of
> tuning, a 'first timer' for me.
> 
> I'll give more clues later if nobody gets it soon.

Screws holding the the blocks which the damper tray pivots in are loose?
