You know, it's funny but there was a site a few years ago that had a very short online clip of what was supposed to be a 1940's CBS color kine, except that they were unable to identify the subject... which I seem to recall was a close-up of a blonde woman. Wonder if that's the same clip?
Along these same lines, I was just recently told about a reel of film that was found on Ebay, which contained two 1954 COLOR kinescope clips from NBC (though they were badly faded)-- a few minutes of an episode of the Dinah Shore Show, complete with a chopped-up but heretofore unknown NBC color ident, voiced by Hugh Downs; and the opening minutes of an episode of Eddie Fisher's "Coke Time", from March of 1954.
Impossible things **are** happening every day!!
