Nice one! It's great when your 'hand holder' on a permission visit goes that extra mile and gives you a little memento. After WW11 there were all types of aircraft fuselages available for modification - some ended up as rather unsuccessful 'caravans' and I can remember seeing two or three as a young lad. Many of the WW11 airfields ended up as impromptu scrap yards and some of these are now just derelict sites, not having suffered redevelopment. If one is a metal detectorist and knows where to look, you can still find scraps of alloy and the odd instrument etc. My wife who lived in Horsforth as a child ended up with a section of Airspeed Horsa fuselage as a den/playhouse. They were being built by a firm on the fringe of Yeadon Aerodrome (Leeds/Bradford Airport now)and vast numbers were never assembled, which were offered as sheds, playhouses etc in the '50's. A couple of sections were still visible on a couple of old allotments around 12 years ago.
