Other than that, I don't know who's the lucky guy who took the picture of these beautiful flying machines...
Silver and red colors are from the Blackpool Air races of 1948/49.
Mk XVI: TD-248 built in Nov 1992
Mk XIV: RN-201 built in June 2002
Maybe would they be enough kind to put you on this picture track...
