 Although I cannot say in which equipment your coax relay was used (RAF,
possibly 50s or 60s looking at the numbers) I can report that we used quite
similar relays (with N type coax connectors) in large numbers in the Philips
(PTI) PMR VHF/UHF base-stations type 8MZ650/8MO650, also known as 'SQ' equipment
(of course with valves) during the early 1960s until the late 1970s.  I consider
yours a variation of a particular model.

I have come across many enclosures similar to this one.  It appears to be of
British military aircraft origin.  I have several like enclosures with various
different functions (antenna switches, junction boxes, fuel quantity amps, etc.
in my Canberras.  It may just be a generic enclosure with a coax relay placed
inside.

Thank you all. If anyone needs it, please contact me off list, since it is not
part of any system I am interested in. Caveat emptor.
