Wigtown/Baldoon it is.
The airfield today still looks to be fairly original, as aerial views of the land show that nearly all the perimeter and access roads remain visible, as do the roads to the various dispersal sites and installations belonging to the original airfield. As well as the roads, the concrete bases of many of the hangars and other buildings can still be seen on the ground.
To the SE (top of the picture) the tracked bombing range sitill exists.
