Thanks, Don, for the helpful information about the various Coinolas
[150615 MMDigest].  Mine is a CX with the Roman columns on each side of
the center glass with the flower vase.  I will look for serial numbers
and try to get them posted.

The stack has two rows of glued-on pneumatics.  The valve covers are
wood.  I've recovered the stack and bell pneumatics with black synthetic
material from Dave Ramey.  I need a motor pulley to drive the pump and
the roll frame.

Thanks again,
Allen Scott
