Sorry forgot to mention in my post above that the Lizzie Landing Gear is Fairly (cough) Large all round - one of the museums (shuttleworth ?) used to have a complete Lizzie Undercarriage Beam hanging on a wall - a one piece forging (?) which looked a little like a whalebone,so the aircraft ended up with large leg fairings and even larger wheel spats,they are pretty large diameter wheels anyway so would require a fair sized spat,not sure if the stub wing/pylon might have contributed to the original spat design ?
