Hi Paul,

I do not know but in middle of 60s that was the only TV color
projectors
designed by a Swiss engineer, assembled by Peto Scott Instrument Ltd
for Philips
in Addlestone, Surrey UK.
It was tested in the central lab were we were mainly working on
military equipments.
Many of those big blocks were sold world wide. I do remember the Mexico
Olympics
because we had to do that special test in the chamber room were
airplanes were
tested for all 3 machines.

For Peru', I believe it was somewhere over 2000 meters asl and it was
not later than 1980.
