A friend of mine recently has acquired two Sirion disc players with
a "disc shifting mechanism".  Now we are looking for getting some
discs for these rare machines.  In detail:

1) Discs 14-1/2" (36 cm), driven from the outer rim, one or two tracks
(melodies) per disc

2) Discs 19-1/4" (48 cm), driven from the outer rim, two tracks
(melodies) per disc.

Is there anybody out there who would sell such discs or who could tell
us where we could find them somewhere in the world?
