LT RTL637, KGU87, on the 29 route at Victoria.
I think this photograph was taken because Cockfosters was either an unusual or incorrect destination. The 29 did reach rural Hertfordshire; on Sunday afternoons there were journeys to South Mimms Clare Hall Hospital which in the late 50s was a TB sanitorium, not sure if there were through journeys from Victoria or whether these were shorts from Wood Green or Turnpike Lane.
