Hi
Your TV looks almost identical to the European KV1300E which dates from
1972.Picture attached.
Sony at that stage were trying to get round the PAL Color patents
& there was a very early UK model which converted PAL to NTSC.
This one also has a hue control on the front which is very rare on PAL
sets so maybe the same.
They are built like a tank & very reliable.
I have a video if it on youtube receiving Italian Rai 1 DX TV on lowband
a few weeks ago

The show was in widescreen format so screen is dark at top and bottom.
Select the "Watch in higher Quality" option to the lower right of the screen.
I can't remember what the "windy thing" is..Maybe the Color purity
adjustment.
