M.K. double sockets with four fixing screws.


Thanks,

    I can give you some quite wide bounding dates.

    1) no lighting CPC puts you before 1970,

    2) but the use of PVC not rubber cable probably puts you after 1960, certainly after 1955.

    This is backed up by the 4 screw socket boxes which are a mid 1960s thing.  (the relevant british standard changed to the 2 screw variant in 1967  but both were in use for a bit)

    Much before that BS 1363 :1947 was in force but for the first decade or so, most sockets were singles and brown rather than cream.
