I just received the following from the original posting:
"This is from Restoring Baird's Image by Donald F. McLean, who was primarily responsible for obtaining the relatively clear Phonovision images linked above. The photograph seems to originally have been published in a book, Popular Television by Barton Chapple (1935). The caption by McLean is:
Baird with phonograph equipment. The original caption by Barton Chapple
refers to Baird 'carrying out his original Phonovision recording
experiments'. --From 'Popular Television', Barton Chapple, 1935
I would say the actual photo dates from before September, 1927, when Baird was using discs pressed by the Columbia Graphophone Company. This is under the presumption that Baird first experimented with cylinders before moving to discs. The only other reference to cylinder recording is another photo on the facing page showing Baird's apparatus for Noctovision, dated 1927, with a standard size cylinder sitting in front of a mechanism with a flywheel and standard size mandrel."
So Don certainly knows about these experiments. This was the first I had seen of cylinder machines used by Baird.
