I am looking for any information available pertaining to a Symphonion
Twin Disc machine.  This machine plays 17-3/4-inch [45 cm] diameter
discs.  The discs are labeled A and B and the spindles on the machine
are marked to receive the A and B discs.  This is an upright format
machine and not a table model.

I have been unable to locate any information.  The Encyclopedia lists
the Symphonion disc sizes and does not list this size.  The bedplates
are labeled "Symphonion Mfg. Co. NY."  Any information or references
would be helpful.
