It would be interesting to examine a photo of one of the UHF strips and/or a schematic. I would guess that the strips were most-likely designed as universal, tuning all UHF channels perhaps via Coarse and Fine adjustments. It would seem most practical for the Coarse adjustment to be accessible from the rear or concentric with and located behind the Fine adjustment similar to double-tuned IF coils. It seems exceptionally likely that the setup procedure would have involved the use of an alignment tool to set both adjustments such that optimal tuning of the desired channel occurred at the midpoint of the range of adjustment which would be permitted by the Fine Tuning linkage after the knobs were reinstalled.
