I don't have any idea of the dates. I was just now thinking that maybe WW2 disrupted the existing "systems" so much
that it meant the end for this. The RCA and Mackay receivers ( both regens too ) dated from around 1936-37.
Much of this topic has disappeared into the smoke of time. I have some transmitter literature for transmitter models
I have not seen described anywhere else. Or just try to learn something about the "American Radio Telegraphers
Association", a craft union.

"Preliminary edition" :
Years back I bought an RCA AR-8501 ship's receiver. The seller told me that at the time of use, mid 1930s, the RCA receivers
were not owned by the ship, they were leased. RCA may have supplied the operator also, under some kind of contract.
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.
I recently found an 'International Marine Radio Company' ( ' IMRC ' ) ship's regen from around 1940. )
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?
I think the photos we've seen show that after a few years, the ship owner, maybe even the radio op, could put whatever receiver
onboard that they wanted. I think sometimes the receiver, like a second receiver, belonged to the radio operator.
The radio operator(s) on British (and other?) merchant ships often maintained and sometimes owned entertainment receivers in the crew's
quarters and mess.
I have not forgotten the deal with the radiotelegraph forms I have; it's just a lower priority now than downsizing .
When did RCA end it's public radiogram service?
