Hi everyone -- Some years ago I got an upright foot-pumped
Marque Ampico "semi-reproducing" piano and am about to complete
the restoration of it.  The only problem is I don't know how the
tubing from the expression units is supposed to be connected,
since nothing is labeled or connected currently.

Does anyone have any knowledge of how these are assembled?  Or
does anyone have one they could take some pictures of?  I've asked
some other restorers, but these instruments are pretty uncommon.

Thanks!
