Hello fellow MMDers,  I'm evaluating an R.S. Howard upright player
piano for possible restoration and I need some help in identifying
the player action.  The piano was build between 1905 and 1910 (serial
number 20757) and has a 65-note player action.  The unusual thing about
the player action is that the wind motor is below the keybed, the
rotational motion being transmitted to the scroll box (scroll box on
top of the stack as usual) via a long chain drive to the far right of
the stack.

There are no markings on the action to clue one in as to the maker.
(There is a "R.S. Howard Player Action" decal in the inside of the
scroll box, but since it was common for R.S. Howard to put their own
name on the Standard, Simplex, and Pratt-Read actions used in their
pianos, it is not a clue.)  Other clues include that the stack is held
in place with two large keys (think clock keys) rather than screws,
one on either side.

The tracking mechanism is not the Standard "two hole" type.  The
tracking mechanism and pneumatic (a single medium-large bellows) are
to the left of the scroll box.  The tracker bar is not a "trapezoid"
hole or square hole tracker bar; the holes have the shape of two
opposing parentheses,  like this ')(', but on their side.  (Sorry,
I couldn't get a clear enough photo.)

The piano, as a whole, is in fairly good shape and has a held a tune,
a testament to R.S. Howard's claim that the pianos are indestructible
and could survive harsh climates.  It even made it through a fire
unscathed with only minor cosmetic damage to the finish on one corner.

Any help identifying the player action would be greatly appreciated.

Many Thanks,
Bradley Matson
