Zenith 40bc50 mystery set

[zeno]

Interesting change in the manual. I only remember supliments,
not replacements. It would also be interesting to see if there
was more than one line folder that year & if the "big book"
ever had pages on the sets published. Or if the sets were in the
specs & features charts.
Probably never know unless we can find an engineer that was in
the color TV dept & still alive. If there is one out there it must be
in the Chicago area..........
