I purchased the custom-built "A" roll player unit offered here
a month or so ago [150820 MMDigest].  It had been connected to
a 32-note calliope, which was sold separately.

I also bought two "A" rolls; one is marked "Clark Orchestra Rolls
A-102X for 65-note Rewind Electric Pianos".  Does the "X" indicate that
the tracker bar scale was modified to accommodate the 32-note scale?

With help from a couple COAA friends I plan to make an air calliope
using wood organ pipes.  Many of the tubes coming off the tracker bar
have a "y" connection to another hole in the tracker bar.  Is there
a tracker bar scale available anywhere for this type modification?

Thanks for your comments.  My email is
