There is also a series of long play, above-keyboard top actions,
the ones with the cone drive.  Bill Koebigsburg reports seeing two,
I've seen three, Mel Septon reports another; that's five.  The
electric Bodine roll-drive motors have serial numbers which seemed
to all be within 20 numbers of each other, so quite reasonably it
was concluded there might have only been 20 of these pianos made.

The most recent one I got was 76 numbers above the rest, raising
more questions:  How many did Aeolian buy?  Were they all purchased
in one lot?  Were they all used?  Bodine has not been helpful in
answering these questions, or in answering questions about supplying
replacements.

I've yet to hear of one of these top actions in a piano other than
a Steinway.  In order to fit it in, the stretcher has to be routed
(carved) out for the top of the spool box.  Actually getting an
original long-play roll in is not as easy as in standard spool boxes,
as the brown Bakelite spool-ends just fit, and the spool-box itself
is rounded to fit into the stretcher.

The spoolbox is shorter than most; so far what I've seen all have
double holes on each end for tracking, and floating tracker bars. 
These pianos so far all have had standard Duo-Art expression boxes,
as have the series of drawer-model Chickering Duo-Arts from the
mid-thirties.

There is a series (five reported) that first appeared in Steinway
pianos, serial dated 1927, which have electric roll-drive motors, not
the Bodine motors.  They have the fan system expression boxes above the
keyboard on the left side, and the stack is also above the keyboard,
behind the spoolbox.  These pianos do not take long-play rolls (so far
as I've seen).  If the serial numbers of the pianos are accurate to
when these players were built, then development of the fan accordion
system would have occurred in 1925 or 1926.  But Garwood was often
reported to be behind in installation, and too these might have been
leftover pianos used at a later date.

The last of the Steinway "D"s (concert grands) produced was serial
number 269100, which would be 1930.  This piano has the above keyboard
fan expression system, the stack and an electric roll-drive, but it is
not large enough to take long-play rolls.  The inclusion of this system
in such a top-of-the-line piano raises real questions in my mind about
the often heard conclusion that the fan-system was a failed attempt to
make a cheap redesign.  I have two of these systems in working order
and they operate just fine.
