On another forum that I am a member of, a question has arisen about the location of Crystal Palace speedway track.
For those who don't already know, the track was sited on what is now the Athletics track and operated between 1928 and 1940.
Now I already know that the whole of Crystal Palace park is located within the London Borough of Bromley, as defined in 1965, but, prior to 1965, was the park in London or Kent?
More specifically, when it was in operation, was the speedway track in London or Kent?
Just for clarification, it's always classed as being one of the London tracks, but we are trying to get more technical, or hyper pedantic, if you prefer

Any info would be gratefully received.
