Its an interesting project, the days of DIY Spitfire re-builds in the UK seemed over when the more stringent regulations pertaining to certification of permit aircraft came in to being in the 90’s. I wonder which organisation Mr Philips is in collaboration with regarding the CAA certification/approval process as now only one of the few companies holding A8/20 E4 can apply for a first permit to fly (this legislation effectivley ended the DIY/sign off by a licenced enginneer method of the 70’s and 80’s).
Good luck to him in any case, it will be great to see ‘232 back where she belongs.
