Hi  Mike,

They are not quite vanishingly rare.  A fair number were  produced, and 
RCA Radiomarine got involved, and sold and supported them  for years.  
Legend has it that they survived on the Great Lakes  throughout WWII, 
after they had been banned form the high seas do to  oscillator radiation 
concerns.

I believe radios like this were the  source of the low-radiation flap.  
It's a regen without an RF  stage.  I once tuned it up on 600-meters into 
a good sized  antenna.  I keyed the antenna lead with a relay driven by a 
function  generator.  I could easily hear it a kilometer away on a 
transistor  portable using the built-in loop.

73,
Al
