Hangar in the background appears to have a sign with a bottom line 'Air Service Ltd' so I'll plump for Heston.(Nice 3 -pointer about to happen)
Note no gun fitted to the turret and no squadron letters. Interesting chimney(?) in the background but no cooling towers so unlikely to be Croydon.
Sorry to ramble on, not much happening at work today!
