I just bought a new Wurlitzer unit valve from Player Piano Company
(PPCo).  It seems they have done away with the extra hole for the bleed
and put the cup in the center of the pouch.

Matthew thought that someone might know what the advantage of this
might be.  When I hold the thing up to the light from the valve side,
it looks like the bleed hole is slightly off center.

I am looking into tooling a CNC machine to make some of these, as the
quality seems a bit off.  Since I have more machine tool experience, I
thought I would make the roll frame and lock and cancel logic first.
This will be for band organ to play Wurlitzer style 165 rolls.
