Thanks for your comments Shawn M and TorbenD..
All pre and post shadings applied during painting process.
This will be finished as Mk.IIa P8088 NK-K "The Borough ol Lambeth/ Bette" flown by Lumsden of 118 sq.based at Ibsley, Hampshire May 1941.
I have no exact idea that this is an early MkII or not. So my only reference was "1/32 Haegawa Spitfire MkII No 41 sqd" kit which also offers NK-K s decals And I have painted it due to Hasegawa s paint scheme.
Your warnings noted for my future project. Thanks a lot for this
