worked in the underground communications centre ( QQCD ) at Fort Southwick and was on duty on "D" day, June 6th 1944.I was also on duty during the Royal visit which took place Sept. 1944 and the published photo was taken at that time - not in the
1950s or early 1960s.
Pat Philmore, in those days was only responsible for the repair and maintenance of the teleprinters. He had a small workshop off one of the GPO main equipment channels.
Regarding the GPO carrier equipment room, location 86 on plan, the fellow in the foreground is Vic Pont and the fellow in the background I think is Sid Scott and not Pat
The tunnel with the people in the picture was the voice frequency telegraph carrier ( VFCT ) room interconnecting all the teleprinter circuits to many other communication centres.
The carrier room for voice communications was in another tunnel parallel to the VFCT tunnel.

[This photo has now been conclusively identified as having been part of the
same series as those above: WWII. September, 1944. Dennis Tammadge's email is
accurate in its detail.]
