Hi MMD,  I have recently obtained a Seeburg A keyboard piano, gutted
case only.  I am interested in dating this piano.  The serial number
is 58220.  It is an earlier A.  It has an angled coin slot and slot
for soft-loud cut out at the bottom of the beveled glass front,
but no on-off mandolin control knob as shown in pictures from the
"Encyclopedia of Automatic Instruments" for A and B pianos.  It is oak
finish, quite good original.  The instrument looks identical otherwise
to the Seeburg A shown in the book.  Thanks for your help.

Musically,  David Oppenheim

 [ vendors for their pianos.  Unfortunately the numbers are not Seeburg
 [ serial numbers but actually the manufacturer of the piano itself."

 [ Art Reblitz wrote more about this in 980311 MMD.  He seeks this
 [ information for Seeburg pianos:
 [
 [   The piano serial number.
 [   Whether the serial number is rubber-stamped or die-stamped.
 [   The piano stack number (on the front or top of the stack).
 [   The pipe chest number (on the top or front of the pipe chest).
 [   The number on the paper sticker on the coin switch box.
 [   The date rubber-stamped on the bottom of the piano hammers
 [   (usually in the midrange, under the hammer tails).
