Mr. Rein Schenk of the Netherlands wrote four articles with a rather
complete listing of Carl Frei's compositions in Het Pierement, the KDV
magazine, in 1975.  I will see if I can translate this list with some
annotations Schenk made, and I will send that to MMD, in MS-Word format.
(It's too long for this Digest, I think.)  Please be patient -- it is
a rather long list!

Happy New Year to all friends of mechanical music all over the world!
