I have a copy of the January 1961 issue of "Electronics World," which
features a transistorized theremin on the cover and contains an article
by Robert Moog on how to build your own.  If you can't locate it, I'd be
willing to photocopy the article for you (5 pages).  The publisher was
Ziff-Davis, One Park Avenue, New York.  I have no idea whether they are
still in business, or where to begin looking for a 30-year-old back issue,
but it looks like it would be fun to play with (if you like winding your
own coils).
