Yes, thats right!
There was a company, still in busyness with house electricity, which
assambled TV sets for italian, american and german companies.
But Telefunken had its own plant since the 30s.
That company received the pre-assambled chassis and mounted the stuff
with cabinet parts, speakers, CRT, etc.
It seems that companies who wanted to sell TV sets in Spain had to pay
unusual high taxes if they don`t give spanish people a job.
Grundig and Loewe Opta sets in Spain were not assambled in Spain.
Maybe they got a better quote.
I have two british 14" sets from Spain, but don`t know of one or both are
produced for CCIR or are only "victims" ( no more 405 line life

) of a moving owner.
