Hi all. I am restoring a Wilcox and White Angelus piano player. Two
"choker pneumatics" (mutes?) are mounted on the organist side of the
tracker tubing outside panel: a shorter one on the base end, a longer
one on the treble end.

A piece of wood to create some kind of pneumatic is missing at the
lower end of each one. There is evidence of old cloth that wraps around
somehow.

I can't determine what the missing piece looks like from the drawing
in the company brochure I found online. Any information is much
appreciated!

Thanks,
Anita Stull
