You could very well be right. I was given the pic to accompany a tender around 1994 or 5 I think. The work could well have predated that by 10 years or more I suppose. Never had a project data sheet for the airfield; we certainly did some work for the RAF fire school.
When I landed there, I recall going into the flying club for a coffee and a pee; must have been 1989. It wasn't far from the runway, that I do know!
