I remember going to a surplus yard, out in the sticks somewhere in South Lincolnshire in the late 80's/early 90's
You might be thinking of Jackson's, at the Old Rocket Site, Misson, Notts. I visited there some years before you and can recall a pile of Shackleton rear fuselages, and maybe a few nose sections, too.
They were (and still are) mainly dealers in ex military vehicles.
