Oh piffle... If any ex-WWII pilots want to complain, then I'll give them a hearing.
Personally I'm glad that there's one company that makes a reasonably close replica, though I know full well I'll never be able to afford it. Nobody in the know will confuse it for the real real deal, so it's not fraud (except for the dummy radiator option). And at least it isn't built out of either plywood or composites.
If they did make a 100% spitfire, what engine would you put in it anyway assuming Merlins are no longer practical?
