I have a Bakelite Stewart-Warner set made this way from 1946. I also own a Mantola (BF Goodrich) that has a conventional tuning cap but a slug tuned RF section with a linkage lever connected to the tuner from about the same time. The only thing about slug tuned front ends you need to be careful of is that the radio be allowed to equilibrate to its environment before alignment. They seem to be a little more subject to moisture in the controls. Why this did not create problems in automobile sets is still one of those little mysteries I have not figured out yet, unless the closed space and temperatures redried them quickly enough that no one noticed a little drift.
