Sounds like an interesting combination of engine and airframe. Back in the 1980s, there was a company producing kits for, I think, 7/8th scale Spit MkIXs (maybe slightly smaller than 7/8th scale), which used the Jaguar V-12 engine. I think the company were either Australian or from New Zealand, and the Spits really looked the part, very like the one you posted, apart from being the 'MkIX' replica, and much more like a Spit than some of those small replicas currently flying.
