The Bob Deford machine is indeed wonderful and has a decent V12 on the front. Of all the Spitfire replicas that have been built it is the best. The Tally Ho is a close second but most of the so-called replicas are ungainly. It’s no criticism of anyone’s endeavour, more that the proper machine is so remarkably beautiful that any attempt to replicate tends to fall short.
The full size Hispano engined Jurca that was built in France 20+ years ago was very pretty. It was subsequently re-engined with an Allison and became grotesque overnight!
