I'm starting my project to build a Calliope, and am in the info needed
mode at present.  I need info on sources for vacuum actuated air
valves, 42 to 44 key keyboards, and player mechanisms.  I've talked
with a company in Ceres, Ca.  that uses "O" type players.  Could I get
some enlightment on the various player types?  What do the various
letters indicate etc.?

Appreciate any info.¶
Thanx,
