My neighbor had the next years model Travler, a 16" model using a 16TP4.
That had a similar chassis but with a one tube continuous tuner, using just one 12AT7. The tuner was made by R/C and two knobs, one for high and low band and one for tuning, 2-6 and 7-13. A strange one at that.

I once had a little 14" Sears 'flat' table model with a tuning system I never seen before or since. It had 3 concentric shafts, the outermost one for hi-lo bandswitch, the middle one drove a pointer, and the innermost one was continuous-tuning.

The bandswitch knob was big, about 3" in diameter. It turned 180 degrees to select hi or lo band. Half its face was calibrated in channels 2 - 6, and the other half in channels 7 - 13.

The pointer (on the middle shaft) was direct coupled to a 'radio-style' tuning cap gang, and pointed to the selected channel.

The continuous-tuning knob (on the innermost shaft) drove the capacitor gang and was verniered about 3:1.

IIRC, the tubes were 6J6 and 6CB6.
