Zenith 40bc50 mystery set

[zeno]

No I dont have one !
But some old threads mention this rarity.
A quote from Zeniths TP-6 training manual.

"The 25cc55 chassis is an all solid-state chassis similar to the
40bc50 chassis ( preliminary data was listed in CM118 ).
Since the 40bc50 chassis was never produced in quantities
for the commercial market, the 25cc55 can be considered
a new, all solid state chassis, introduced for the first time. "

Other references are that the power supply, vert, & hoz
are almost the same. The 9-75 replaces the 9-48 vert
module in the 40bc50. Anyone got an old price book ??

Also noted was Zeniths first varactor tuner ( C line) with "3 band lights &
a tuning meter". Never seen one myself. Shows pictures,
looks very Zenth.

Anyone ever find more on this set or check Zeniths archives
( if they still exist ) ?
