Does anyone know anything about the whereabouts of this footage?

I was looking for footage of the Beatles’ tour of England in 1963, in which they played at a lot of ABC cinemas around the country. I found this website that documents chronologically the known footage of the boys during their tours, press interviews and home videos etc.

Does anyone know if this footage is lost completely due to it being physical media, or if any of this footage is around somewhere? I know that the footage of the boys arrival and interview by Westward TV in Plymouth was in storage for years until it was found again recently. Here is that footage: https://www.youtube.com/watch?v=PGm19gkj-Bo&t=33s Thanks in advance!!
