I now have a customer with an Apollo that was rebuilt decades ago.
There is a miniature air motor (4 point) that I think is really neat,
considering how hulking wind motors can be.  It is so small that
I can hold it in my hand, with fingers bent up around the sides of it.
The governor is 4 inches long by 1.5" x 1.5".  Why couldn't they all
be this tiny?

My problem is the little gear -- 1/3 of a pie slice -- with a set
screw for the shaft.  It is pot metal and is now unusable.  Who has
replacements?  I guess I should buy several of them since I have four
Apollos in storage besides this customer's piano.  Does Bob Streicher
have these made up?
