About two years ago someone asked me if I could find some of the very
rare Polyphon discs with a serrated edge drive for the Christmas tree
stand model. I have found these discs 7-11/16 inch or 19.5cm diameter,
numbered in the 7,000 series.
I have forgotten who asked for them so do contact me if you are reading
this. These are not, of course, the same as the movements or discs of
similar type used by Monopol, Kalliope and Symphonion among others in
Christmas tree stands.
Full details are in my book "The Disc Musical Box," of which Nancy
Fratti still has some copies for sale.
