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
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
