OK, sticking my neck out with my intended build:
NN660, the short-lived first prototype for the Spiteful
Source: http://ipmsuk.proboards.com/thread/5630/supermarine-spiteful-1st-prototypes-colour
I'm not actually sure how I'm going to attack it yet- I've got Falcon vac Spiteful and XIV fuselage, and I'm tempted to try to do a vac kitbash, but may go with an injection fuselage instead.

[Edit: 28 Apr I'm going to try to do a production Spiteful as well.]
