Found these TVs here in the Netherlands Europe. All are 525 lines 60Hz, in the Netherlands 625 lines 50Hz. Nice additions for me.

Wow that's quite a collection! How did you find them, and how did they wind up in the Netherlands?

I collect American TV sets here in Spain, most of which I think were brought by people stationed at the military base in the south of the country. I even have a never-used Predicta Holiday similar to yours that was left in a flat in Madrid that belonged to a US Embassy employee who disappeared in 1961.

Disappeared (!)

(back then, that could mean a few things...)

Heeey! Westinghosue 17TV7C in the third photo! :banana:

That is an impressive number of sets to bring across the ocean.

That Stewart Warner is interesting , never saw one

Does anyone know what the small knob directly above the channel selector does on the RCA set (picture #4)? Fine tuning?

Yes, fine tuning. That looks like an RCA T-100:

This one has been sold in the French part of Canada

I need a channel selector knob that looks exactly like the one of the Philips TV seen on the last link.

The RCA T-100 now has a picture. After replacing the electrolytic capacitors.
