It was definitely better than the usual V-M
viewer and I think also a bit better than
their high magnification viewer. It looked
like the eyelens was an achromat. Probably
not for color correction, though, since I
think the screens put out a fairly limited
band of wavelengths.
This one said on it "Varo Optical, Chicago"
It looked pretty old. The tube looked like
one of those RCA 1P25s or whatever they were.
Varo equivalent of the RCA of course. Maybe
it's smaller than the RCA tube. Definitely a
high voltage tube, though.
