Years ago I did an article called "Commanding the 11th; the service career of Capt. Charles Heater" for OTF. Before taking command of the 11th Aero, Heater was a pilot in RAF 55 and he flew out of Azelot field. At the time I was mainly concerned with getting Heater's memoirs right and I didn't put much effort into researching Azelot field, but I do remember that it was mentioned many times in the text of the article. Perhaps you can glean something from it.
If you don't have Volume 3 of OTF, you can find the article online at
