Compressed air sets were widely used by many bridges at that time. We were using them in Manchester along with most adjacent brigades but still ran with one hour Proto sets on the ET. Training on Proto was continued till 1972 with a two day conversion on air t the end of the two week course. Proto on the ET was eventually dropped about 1973, maybe '72.
From "One Hundred Years of the British Fire Engine" by Neil Wallington (2008): AEC Merryweather 100ft turntable ladder formerly delivered to Croydon Fire Brigade in 1963. This fire engine was absorbed along with the fleets of nine individual brigades into the enlarged London Fire Brigade (LFB) at the inception of the Greater London Council in 1965. After being finally retired from operational service in the early 1990's, CBY 1 was preserved by the LBF as a classic working example of its time and today this turntable ladder is in regular use at fire service charity events and other functions.

Here is a little info on this video. The morris side is Beaux of London City & the fool in the big hat is probably either Jack Hamilton or Hamish Frazer. Jack, co-founded Broadstairs Folk Festival. The jackets were called “Forest of Dean jackets”, not “Tatters”. There is a photo of Alec Hunter, the first Squire of the Ring wearing one. When they danced they always processed on out of sight round a corner and when they arrived at the dance site began dancing immediately. The last time Beaux danced was in Broadstairs some years ago when a seat was dedicated to Jack Hamilton in the Dame John Gardens. Jack features as the morris fool in the “Great St Trinians Train Robbery, while Westminster M.M. dance “Queens Delight”, though he is upstaged by Frankie Howerd who takes over.
