Leigh,
The last photo of 'Control No 20' with a Sect/Ref No 14A/3208, is from part
of an aircraft camera system, possibly relating to film exposure control for an aircraft camera or camera flash unit exposure control.
As the Ref no is only four digits (they later became seven), it probably dates
to the 1950s or 1960s; it may have been used on PR or MR aircraft such as
the Valiant, Canberra, Shackleton or Nimrod MR.
If you can record any of the text on the other instrument, I will try to look it up (I can't see properly from the photo due to sight loss).
