It seems that Mr. Keller (Dr. Keller?) makes a misrememberance. He 
states that Vitaphone discs were 16 inches in diameter and were made of 
shellac with abrasives. If memory serves correct, Vitaphone discs did 
NOT contain abrasives, and thus had a strictly limited life of about 20 
plays.

The stereo recordings are quite interesting. I presume that this is a 
spaced pair.  I would honestly love to hear the sound of Blumlein's work 
in England, but for reasons unknown to me the short extracts contained 
in EMI's Centennial box set have no separation at all. They don't 
"sound" stereo, and I've tried everything from phase inversion to 
channel reversing. Maybe I got a disc from a bad master. One would 
expect a "Blumlein Pair" recording to have depth, but not the Centennial CD.
