does anyone still make these?

I doubt it. Black and white TVs wouldn't have been made for several decades now.

If they still make them I doubt anyone would buy one unless they were dirt cheap.

I remember a small black and white TV we had in the 80s... It had a FINE TUNING knob which made it easy to tune scrambled signals in :D

Why would I want to buy a black and white TV? My current TV shows black and white programming just as it looked 60 years ago. No adjustment nor adapters necessary.

I doubt that.... These current "TV"s show flat digital garbage!! (No detail at all)

Nothing like what it looked like then (Beautiful warm analogue)
