Hello Troy:
Thanks for the good information.
In fact the C wing could be fitted with the E armament arrangement, which was happening around D-Day IIRC.
I was not aware of this,but I knew that the kind of rudder was not tied to the type of wing.
At first,I identified the type of wing of the Spitfire UTI by the light bulb on the leading edge of the wingtip.But recently I discovered this picture of the same plane taken from a different angle,showing the wing.

The source is one of the Monografie Lotnicze about the Spitfire.
I don't if the VVS even got E wing spitfires though.
if you have not checked it this will be of use
http://spitfiresite.com/As far as I know,most of the Spitfire Mk.IX that were sent to the URSS,had the clipped "e" wing and pointed rudder.And I already know the Spitfire Site,an excellent source of information for Spitfire followers.Thanks for pointing it out anyway.
The Spitire UTI photos are very scarce,I?ve seen another with pointed rudder but is of bad quality.
Hello spokito:
why did you stopped the bilding ? to much boxes open ?
That?s right,this and the difficulty to build the translucent "tunnel" between the cockpits were the reasons.
Greetings to both of you.
