gyp I hade heard of the infamous castoring (cross-wind) undercarriage but never seen a picture of it before. Apart from what appears to be a big hinge on the wheel hub it looks remarkably standard. As I understand it, this option was not the most popular one Auster ever offered
PS the Auster in the pic appears to be a Cirrus engined Autocrat with the bent steel Fairy-Reed prop. The wheel hub covers look neat, they tidy up the wheels very nicely. Mmmmm must speak to my friendly parts supplier and get some. Got to be easier than fitting spats...........
