That set has a surprisingly rounded tube for 1961. The black and white sets in the UK were fairly rectangular by that time, although most still had a separate armoured glass safety panel. That colour one looks like it has a bonded screen.
Ditto for Oz,although the separate armoured glass panel had pretty much disappeared,replaced by a panel manufactured as part of the screen.
23" BW tubes displaced the more rounded 21".
Philips & Kreisler had wired remotes which from memory only did vol & brightness/contrast.
The short-lived (in Oz) Ekco brand had an ultrasonic remote (with tuning forks),& a big ,boofy motor in the cabinet which turned the tuner via whar looked like a bike chain.
Press the button ,& the tuner rotated-"chunk,chunk,chunk!"---you stopped at the channel you wanted.
At the time,I would see ads for the Zenith Colour sets in Playboy---No!,Honestly,I only read it for the articles!
All of them had the roundish tubes----apparently the early delta tubes were hard enough to build, (& converge),without introducing a new tube geometry.
I have obviously elevated nyself to Geek status---I remember TV ads from 1961,without remembering anything about "Miss January" or an of the others.
