I went to take a closer look at the Cicilian stack that I wrote about
last week. The owner said it was a 65-note. In reality it is an 88-note
stack with interchangeable tracker bars (it has both bars).  Flip two
small levers, take out one bar, put in the other and off you go. There
is a soft gasket that seals between the two blocks (the fixed block
that has all the tubing connected to it and the two interchangeable
tracker bar blocks) that are clamped together by the small levers.

Also, the foot pedals are missing but otherwise the pump bellows seem
to be complete.
