I just found this (under a home-made blanking box) in the sixties

It's in the kitchen wall, just below and slightly to the side of the
electric switch plate for a cooker: until I removed the covering box I
assumed that I'd find a 45A cooker connector, but it clearly isn't
that (and on a side note, though there's an empty conduit buried in
the wall from the base of the cooker switch back box, it doesn't
emerge anywhere at all) - so is it gas?

Yes it's gas
