Zenith numbers tabs

[drh4683]

I can't say that I recognize those either. I looked up the part number in my Zenith parts manual and nothing is listed for 102-9224. But going by the design of the tuning knob from the diagram, it appears to be the tuning knob with the floating channel window as used on the 1959/1960 models. Some of the trapezoidal ones seem quite large though and may not fit that particular knob.

They're in my 1968 Zenith Knobs index master table - they give the prefix 102-92 as being indicator tabs, with the channel number being the last two digits of the part number - they only go up to 102-9257, so UHF assignments for the period probably only had channels 14-57 occupied. No data in the "last year" column, but some have SC1, SC3 in the remarks column - Space Command 100/300??? Seem to be universal to Zenith knobs for a set period of time. I recall the first UHF assigned channels using the tabs being on some Hotel/Motel sets - perhaps they were for those sets? We didn't service them, but had a friend's shop that did almost all Hotel/Motel and rental TV repair - he was 50 yards from the beach...
