When the RAF / Air ministry ceased to have responsibility for its real estate, some of its vehicles and plant were transferred to the Ministry of Public Buildings and Works (MPBW) ** FUL is part of a large block allocated to the MPBW. I have 37 FUL on my database as a hardtop. Over the years there has been much discussion as to the colour schemes of these airfield lighting trucks, in addition to RAF B/G with yellow, red and white was also used for vehicles whose primary task was in the active flying areas ie the runway, its approaches, taxiways and flight lines.
