Pictures were scanned without much of the text including model numbers, so I wonder if all those are 1971 models. The 1971 23" lower-end console of my youth is not among these but there is one with the same control layout in Italian Provincial near the end.
The first of the hybrid color 19-inch models (party girl and balloons) using chassis 4B25C19. I had one for my first apartment and it was AWESOME, but had to sell it to pay rent
.
For instance, I never saw the banana-handle knobs (tennis couple set) on anything later than 1968 models. Maybe the left over knobs were saved for the later, lower priced sets.
I was certain the single-knob channel selector on the metal cabinet large-screen model was only on 1968-70 sets.
Id love to have this brochure, time to check epay...
