Recently I was able to acquire a J. P. Seeburg Electric Grand Upright
piano.  It seems to be all intact, from what I can see, including the
coin mechanism and box.  Although I have rebuilt several foot pumpers
in the past, this is my first coin-operated piano, so my question is,
does anyone know where I can obtain any information on restoring this
piano, more specifically the coin operation?
