Sorry Andy, I had not realised the link was there. I had already decided that was the probable location on the 1948 6-inch map, but your later 1:2500 edition actually says "RAF Station". It must have remained in use for some purpose, so survived longer than most. I had got lost on the ground with Streetview!
Thank you, Ross. Some time ago there was an uploaded history of the station at Sutton on Hull, which served the city of Hull, but it has been taken down. I took some copies from it, including a plan. Unfortunately I am unlikely to be able to visit Hendon.

The one I am actually interested in is Bishopbriggs, which served Glasgow, where my father was posted for about 14 months in 1940-41. It is shown on this map:
