The Essex Aero Sprite was a two-seat, low-wing design with fixed tricycle undercarriage and a V-tail — bit like a small Navion with a Bonanza’s tail. I think the major parts of the whole airframe were magnesium, not just the skinning. A retractable gear version was also planned. The prototype was built at Broxbourne and was reportedly well advanced, but it never flew — one of a number of now all-but-forgotten post-war British light aircraft projects that came to naught.
