Hello Al,

Yes, thank you very much

Nick England has also quickly schooled me on the “digital” word :-)

"Optical Projection" is where I was initially trying to go

and roger on the Montgomery Ward and Airlie “Movie Dial” civilian radios

also thanks to Robert Lozier of AWA there were Marti civilian set with Veeder Root dial but not projection- http://uv201.com/Radio_Pages/Twenties/marti_console.htm

Maybe I should expand this presentation a bit.

I really appreciate the feedback and all the best,

Brian,

I'd be really careful with the word "digital."  AFAIK, the E-52 is a projection of an analog dial to achieve better tuning resolution.
This goes back at least as far as the Ward's Airline Movie-Dial Radios ca. 1936.  (I'd post a picture, but this reflector is a DAMN MESS!)

Even the Collins R-390, ca, 1951, is just a Veeder-Root style turns counter on an analog PTO.

I'm not sure we see a real digital display until ca. 1966 in the Watkins-Johnson 357.

My two cents,
AL
