I recently acquired 6 paper disks marked "MUSIC-DISK for Lawrence Welk's
Music Maker".  They are 7-1/4 inches in diameter, about .020" thick,
with a1/2" square hole in the center reinforced with metal.  There are
10 tracks around this disk with holes punched that are 1/4" in width
and vary from 1/8" to 1/4" in size.  They are apparently for a
harmonica based instrument, since they have  a START point and several
BREATHE points around the disk.  Has anyone seen one of these
instruments and what does it look like.  Incidentally, it was
manufactured by the Kenner Products Co. in Cincinnati, OH.  Any info
anyone can provide will be greatly appreciated.

Thanks
