("Insulation - Attic" in the GPO system!)

Probably more like "Insulation - Loft, No. 18", even though 1 to 17 doesn't exist...  ;D

....found this old illustration at bridgeman art.

 "soon one will see the person one is speaking to, from as far away as one can hear them on the telephone."

Idea for a video-phone using neon tubes to give the picture display. Illustration of a system proposed by Herbert Eugene Ives (1883-1952), American physicist and inventor, who worked at the Bell telephone laboratories on the transmission of mechanical video images. From Le Petit Inventeur. (Paris, c1927).

Remember that the Mod 1 Picturephone was always a research/demonstration effort.  These were never intended to be put into general use.  As such, they probably included the counter for engineering/reliability purposes, although we still don't know just what they were counting.

Counter mystery solved: The counter advances each time the viewing angle of the Model I Picturephone is changed. Apparently someone wanted to know if this feature would be used and if yes home much. Interestingly the Model II Picturephone doesn't have this feature.
BTW removing the glue residue between the safety glass (in front of the tube) and the actual tube dramatically improved the picture quality.
