There was, sort of, I had a valve car Blaupunkt radio

I have an American made AA5 in the shop that is also
graduated in wavelength rather than frequency.

But my personal favorite is one with 1500 on the left and
550 on the right.

I have radios marked 0-10 or 0-100. They're fun to use.

Some late 20s superhets used a 0-100 scale, in keeping with the TRF three dial scales.
