Hello everybody,  I wonder if anyone has the trackerbar layout
(hole assignments) for the small 20-note organs built by Raffin
and John Smith?  Also, I want to know the diameter of tubing used
(1) to play the pipes (no valves) and (2) to supply air to the spool
box to play the pipes.  I am building a small organ, which is the
reason I need these.

Oh, one other thing: does anyone know a supplier of brass and rubber
tubing besides Player Piano Co.?  Thanks.

Sincerely,
Andrew Barrett
