Thanks Steve,

It's pretty well established now that the BBC did give limited colour cover of the Coronation in 1953, `though people still disagree as to whether it was by landline or short range broadcast, or come to that whether it was Field Sequential or early NTSC. The BBC don't seem to have any records of it, or none that they'll admit to. I wish I knew more about this, but I've read a description of an early colour television by Baird in which three electron guns were mounted seperately; two behind a translucent screen which was ridged at the back and flat at the front. and one in front, set at an angle and firing back towards the screen. One side of each ridge at the back would be coated with one colour phosphor, the other side with a different colour phospher and the flat front with the third colour. From memory, this screen was set across the middle of the tube. Viewed from the front, the picture would appear to be in the middle of the set rather than at the front........ Jim.
