Hallicafters used 3 knob designs over the years. the knobs on your unit were the last of the black knobs.

they? switched to Gray in the 60's but kept making the black knobs for the older receivers they were still selling

also look inside at the chassis it should say either run 2 or run 3.

Tony, you say I have one that was next to the last run. How did

you determine that? Bob w8exv?

I missed the earlier threads on this subject. My SX-100 SN 132612 has black knobs. There is no indication inside or outside if it is a ""Mark" model. Is there a list somewhere that relates serial numbers to when it was manufactured?
