        Do you know how long this "lease only" arrangement lasted? RCA 
and Western Electric  were very nasty about this regarding theater sound
        systems as well until the late 1930s when Congressional action 
ended it.  A company many of us are familiar with arose from this. Western
        Electric divested it's sound equipment service company, it 
became the All Technical Service Company. Later, it merged with the Lansing
        company, to become Altec Lansing.  I don't know the exact 
details, but there was some connection with James B Lansing- or JBL.  
Both Alec
        and JBL are sort of still with us today.

       IMRC had a connection with Eddystone in England, they built a 
HUGE desktop marine receiver. It is called the Eddystone 700 or IMR-54. it
       looks like an Eddystone of that era, but it's 150% the size- over 
two feet wide and weighs accordingly. It's a well featured superhet, has 
series
       string/hot chassis design, and basically operates on 120 volts 
AC/DC.  Additional, optional, "power conditioners" allowed it to 
operate  on 220
        volts AC/DC as well. Does you IMRC regen set operate on a 
variety of voltages?

     The radio operator(s) on British (and other?) merchant ships often  
maintained and sometimes owned entertainment receivers in the crew's
     quarters and mess.

     When did RCA end it's public radiogram service?
