DuMont and Crosley made some really cool televisions in the late 40's/early
50's. That Mallory Inductuner was great: continuous tuning from 48~222 MHz
(Ch. 1 - 13 plus CATV channels 14-23 and FM radio) I really like their table
models. Also IIRC, these were the only brands to use a tuning "eye" tube.

I remember seeing Inductuners at hamfests: repeater builders used
them for some purpose that now escapes me.

Yep really cool

BTW: I just did a Google search and it looks like they are still being made!

They used another version in some UHF converters, as well. I think
that some hams tried to use them for 432 MHz tuners.

Since they were continuous coverage, they were simler to reuse than turret
TV tuners.

The only project I remember seeing was in the Bill Orr Radio Handbook from
the fifties at the local library forty years ago. Some project that used
the Mallory Inductuner, somehow defined enough that I remember all these
years later, but it seemed as if the reader was supposed to know what they
were, while I remember seeing little or nothing in all the ham magazines
that I've read (going back before I started buying them new in 1971).

UHF TV converters were often modified for amateur TV in the 420MHz band,
it being simpler than going inside the tv set (assuming it had a UHF tuner
already) and modifying that. By the time amateur TV took off, nobody was
building their own tv sets (which seemed to be something dating only to
the early days of tv).

The UHF converters were floating around used and cheap or free,
starting in the late '60s till the early '80s. What more did a real ham
need than that combination? :)
