All the recent advice on picposting has encouraged me to have a go. Hope it works.
The photo was taken at Croft (S of Darlington) in June 1949 and shows an Auster fitted with a castoring undercarriage. It's display caused much amusement as it charged about the airfield in a series of sideslips with one wheel in contact with the ground occasionally lifting off the change direction/wheel.
The pilot was, I think, Ranald Porteus who also devised the avalanche aerobatic manoeuvre.
