Benny Hill and his fire brigade in "Flying Machines"

British comedian Benny Hill is known for one or more fire brigade skits in "The Benny Hill Show" such as this one. I was just re-watching "Those Magnificent Men in their Flying Machines"; Benny Hill appears in the movie as chief of an airfield fire brigade.

Although the movie was released in 1965 and "The Benny Hill Show" ran from 1969-1989, he had an earlier show (1962-1963). My question is: were the fire brigade sequences in the movie a reference to skits in his earlier show, or was it original to the movie and recycled in his later show?
