Hi to all,
@Dude111,
Eckhard Etzold's site has been archived on the ETF database.
He was a German Protestant priest and passed away around 2010 (from memory). He had great knowledge about pre-war television.

more info & detailed photos on the E1 "Volks Fernseher" prototype, see link.
The 1939 true rectangular CRT was 15 years ahead of its time, it used a flyback EHT generator, revolutionary in 1939 and only 16 tubes.
