Vanguard Building on A40

As a lad, the highlight of a drive into London on the M40/A40 was a quick glimpse of the Spitfire at Northolt…and also, I seem to recall but could be mistaken, one atop this building…

I know there was definitely a Hunter up there for a time, but was there also a Spitfire, real or model, at some point? I bet if there was someone has a photo…

Cheers
