On display at the wonderful Newark Air Museum. Let me copy exactly the wording on the small plaque visible on the trailer. "Originally thought to be XH177 it now looks as if it could have other origins. Used at Boscombe Down by the A&AEE for experimental duties it arrived at the museum via a museum in South Wales in 1998".
