Gary Crawford posted that he is looking for 4-port tracking system
hardware for a Duo-Art Weber.

I have a double-pneumatic valve block assembly for a 4-hole tracking
system, but I doubt it's for a Duo-Art.  I have no idea what piano
system this came out of.  It's not like the one in my Autopiano,
and therefore is probably not like the one in a Standard system.

But it's complete -- both pneumatics and the valve block.  A diagram
of how to hook up the hoses is on the back of one of the pneumatics.
Contact me directly if you're interested.  I can send pictures.
The price is right: it's yours for the cost of shipping!

From rainy California,
