Meatbox EE549 is also a former World Speed Record holder as well, when Grp.Capt Donaldson of the High Speed Flight achieved 616mph in 1946.
Hopefully both aircraft will stay at Tangmere museum.
The other one that I'm surprised to see listed, is the Fw190 A-8/U-1, which for many years was kept in running condition at St.Athan. Its the only surviving 2-seat Fw190, and one of only a few non-crash site recovered examples in existence, and the only Fw190 on the RAFM books. So, quite how someone at RAFM can quote that as being 'duplication' is beyond my understanding
