Bob Stratman, in Digest 961222, asked for information about his Melville
Clark Apollo Expression grand piano.

I think I can offer the help you need -- I restored my Melville Clark
Apollo expression piano about three years ago.  I'm sure Art Reblitz'
book, "Treasures of Automatic Music," has the tracker scale you're looking
for, and I can send you a copy of the page you need.

Your piano sounds like a Solo Art Apollo, which I've always wanted to see.
The two stacks is what gives it away: they used a huge roll (15 inches
or so wide?) with 9-to-the-inch spacing by which, in addition to the
standard note range being available and played on one stack, a second
range of SOLO notes was perforated and played on the second stack,
presumably at an increased pressure level.  Have I guessed right?
I believe Durrell Armstrong, of Player Piano Co., is also restoring
one of these.

I live in Grayslake, about half-way between Chicago and Milwaukee, and I'd
love to see your piano some time.  You are also welcome to inspect mine,
if you're interested .  The expression mechanism is working properly,
but mine does not have the second stack.  I'm curious how the expression
system is incorporated into your piano; I'll guess it plays standard
Apollo 11-3/4" expression rolls in addition to the Solo Apollo rolls.

Why don't you either email or call me when you get a chance (847-548-6416)
and we can talk more.  I took good notes while I restored my piano, if
that's any help!
