It is likely that this was the shelter associated with the decoy airfield at Suffield (NHER 14980) which was constructed to lure night bombers from RAF Coltishall. The description given above matches the specification for a 367/41 shelter (information from S1) which were constructed on Drem Q decoy sites such as that at Suffield. Shelters provided accommodation and protection for the operating crew, housed the generators powering the lights and provided communications, through a telephone line to the parent station. Shelters were placed 400 yds (365 m) from the flarepath which was aligned SW-NE.

The specification for this type of shelter was issued in September 1941 to accompany the new Drem layouts which required an extra generator to power the larger number of lights. The new design addressed flooding problems encountered by its predecessor by locating the shelter above ground and covering with earth. The shelters had three rooms; an engine room housing two generators set on concrete engine beds, an operating room with a telephone, control panel and stove with an extra entrance, and an entrance passageway linking these two. The shelter has staged external expansion chambers linked to the engine room by pipework to prevent external generator noise and a headlamp platform on its roof. Both entrances were protected by external blast walls.The shelters were constructed from brick, concrete and corrugated iron.
Google Earth imagery suggests the shelter has been destroyed, although this is unclear.
