The mysterious RAF Sergeant from Gatow

At the Tettenhall Transport Heritage Centre we are wrestling with the restoration of the Demoiselle replica we have kindly been gifted by the RAF Museum (BAPC.194). During its career it is said to have been restored by an RAF Sergeant at Gatow. Does anyone who he was , because we have lots of queries ? And if indeed it was at Brooklands for a while, can anyone there help us with photographs, or details of how it was erected ?
