Please excuse the slow reply but I was out of the country (and email contact) this past month, returning late last week.
     The memorial honoring Bill Gardiner was written by several of us (and I confess I do not have the final version) and I was not aware that he was preparing a book on the subject you mention (which would not be a typical research topic for him, but Bill was interested in everything).
Sorry I can't be of more help.

Best wishes,
