This tube was made for the Fernseh
A. G. FE-IV set in 1936. These sets were placed in public viewing
halls for people to view the 1936 Berlin Olympics. David Boynes had this information:
The manufacturer is Fernseh Aktie Gesellschaft,
a company I believe had links with Baird in the early thirties.
The CRT has a similar appearance to the 15" Cathodevisor
employed in the 1936 Baird T5. I read somewhere that the Baird
electronic TV sets used a lot of Fernseh AG technology. Indeed, I
believe that the intermediate film technique was also a German
idea.
