Hi Herb, After your phone call to me earlier this week, I decided to
see if this old email address I have for you still works.  I wanted
to give you the Mechanical Music Digest's archived postings about
Ruth band organs.  But our phone connection was so bad that I didn't
try.

If you click on this link to the MMD's Archive page it will take you
to all the past MMD postings about Ruth organs   Then by clicking on
the posting date preceding the posting title you want to read, the
posting will open:

  https://www.mmdigest.com/Archives/KWIC/R/ruth.html 

Maybe there you can find the information you are looking for.  If not,
you can post a question or comment to the daily MMD, by emailing to
this address:  rolls-1701@mmdigest.com
