Hello all,  This will be my first posting to MMD, although I've avidly
read its postings for several years now.  I have an older Coinola
electric piano (Style C?) that came with the A-roll spool frame, but
was missing its stack.  When a stack came up for sale on eBay recently,
I jumped at the chance to get it, but I discovered too late that it
does not match with my piano.

On the stack I have, the pneumatics are, from bass to treble, grouped
as 11-27-17-3.  The push rods all align to lift at a single level.
The Coinola piano for which I need the stack, however, would have its
pneumatics grouped as 13-30-15.  Each lifter on the piano is staggered
at one of 4 levels.  Ideally I'd like to trade the stack for the right
one.

I also have a Seeburg F that is missing its stack, so that would be
another trade option.  Any thoughts or suggestions would be
appreciated.
