Look at the crew! The camera department and the make-up or hair designer, all parkas and Belstaff, look pretty much the same today.
I particularly like the Continuity lady, or the Script Supervisor as she would be known these days. I immediately IMDB'd her: Doreen Dearnaley - Continuity. She has a string of credits from 1949 through to 1973 including Carry On Camping, Up the Junction and Quatermass and the Pit.
I hope she wore her red hat on all of them.
