I used to have Viesna (spring) - https://www.turbosquid.com/3d-models/ussr-tv-vesna-c-276-3d-...

It even had an additional electronic component which made it accept PAL signal, in addition to its native SECAM.

PS: Some say SECAM was technically superior to PAL, but dunno.

SECAM had somewhat better colour accuracy, but was difficult and expensive to work with (at least until digital editing showed up, but it was a bit late by then...)

I think SECAM and PAL were roughly equivalent and both had better spatial resolution than NTSC but the 25 Hz frame rate never sat well with me.
