1957 CBS Cinderella kinescope: possibility of colour recovery!

[Aussie Bloke]

G'day all.

I was previewing the kinescope recording of the 1957 CBS colour broadcast of Cinderella https://www.youtube.com/watch?v=C1F4YhBOA14 and I can literally see chroma dots in the picture which means the colour information in this kinescope film recording is present. I've attached a snapshot strongly showing chroma dots.

So I think it is quite possible the colour can be digitally restored using the colour recovery method developed in the UK https://www.youtube.com/watch?v=CjK-b4x9ZmQ which was used to successfully restore colour on BBC programs like Dr Who, Dad's Army etc. that were in colour but recorded to B&W film. More info on colour recovery can be seen here https://en.wikipedia.org/wiki/Colour_recovery

Does anyone know which CBS archive or independent archive holds the original film print of this program?

I personally think the original print of this film should be scanned at 4K upwards quality and that chroma dot colour digital colour recovery method applied, I'm sure much of the colour will be recovered! I wonder how many other B&W kinescopes of colour programs out there have the chroma dots too?
