It is a Mk.III, the last of the A-31 type. As far as the naked eye can judge, the zero Angle of Incidence is obvious. Just forward and slightly below the the front cockpit is a strange thing on the fuselage which I cannot identify. It casts a shadow - it is real. Almost like a (very bent) panel hinged at the top (or a canard wing !). But all VV engine panels came straight off. Never saw anything like it. Any ideas ?
Oddly enough you really need the help of one of the last few surviving RAF VV pilots who is now probably the Worlds expert on the RAF VV aircraft and their operations and that is.....ermmm probably you. I will have a look.
