The BBC did try color on 405 but mostly experimental. Sets were produced for demonstration but not sold to the public.

A great collector, David Boynes in England, restored what I think from the notes is a Pye 405 color set (mostly RCA tube imports and Pye designs from there) and from that modified a B&K generator to produce 405 color. I can only find his notes on the ETF site and they mostly document the B&K mods...not the set.

And a BBC doc that shows color at the very end. Not a kine but a film shot on set.

The notes have an interesting entry of finding a Mullard (Holland) version of the 21CYP22. Perhaps there were other 21's made under license by Mullard or others and can be searched in Europe. Jerome H...any help on this thought?

Mods...if this is drifting too far afield please restart as you wish with a new topic.
