Replying to David Dunn's note in the 110512 MMD, the Recordo does not
need an on/off switch, since all the expression holes are beyond a
normal tracker bar.  The rewind hole, as I'm sure you know, is the
farthest right on the left side.

On my piano there is a replay switch and the tubing is a bit
complicated.  I wouldn't bother with this, as the replay is quite
brutal: the roll is rewinding fast and it grinds the gears when going
back into play.

There were at least four different Recordo systems, and I have several
tubing diagrams which I can scan and send to David.  What is the
approximate year, and is it an upright?
