I have a Marshall & Wendell piano with a Marque Ampico player unit.
It is an Amphion with an upside down valve.  Most of the hose was
intact when I restored the mechanism but some was brittle and had
broken off before I got it so I am not sure it is hosed properly.
I am wondering if anyone has a hose diagram for it.
