DeepC, it is indeed, the only survivor so far as I can recall.
Thrice rebuilt, I think it looked better after the Storey/Barraclough endeavour which restored it to original Percival spec.
A subsequent rebuild for Des Penrose saw it reconfigured to the Henshaw spec - not as attractive, but true to history!
A lovely aeroplane, sounds great! Hope it appears (with the Arrow Active) at a show I'm at next year. Back to their old hom,e at Shuttleworth perhaps?
Great pics Rob!
