I would guess the 60's or 70's looking at the design of the box. I guess one clue is to see if it's marked BT/Telecom (with the old T logo) or Post Office (P.O.) Telephones. I know the manhole cover in front of the one close to me is P.O. Telephones but the cab has no mark on it other than it's number.
Hmm, does knowing this much make me sad?

Should we start up a new "cab spotter" instead of train spotter title?
