I spent an afternoon at Croome Court (National Trust) with SWIMBO this week, and we visited the small museum devoted to RAF Defford, the adjacent airfield that was used during and after WW2 by the TRU.
I confess I hadn't known about this base, and had an enjoyable chat with a couple of volunteers who'd been stationed at the base during the '50's.
They also have a bomber Canberra cockpit on display. Also in the museum they have a display of 1/72 models of most of the planes that flew out of the base, testing radar and ecm systems.
