An amusing little series recently on Channel 4 (or 5??) called “Auction House” filmed at Lot’s Road Auctions in Chelsea. Twice there were glimpses of “an aircraft wing” being carried in but no film of it being sold.
Highly polished it could have been a DH Dove tailplane/elevator and is by now, presumably, hanging on the wall of some Chelsea mansion.
There was also a scale model of Alex Henshaw’s Mew Gull apparently for sale.
