Well Mal it seems i made many mistakes!!!
:-) :-) Which i am aware off!
Well lets see!
The paints are Humbrol Matt65 light blue for the bottom
Matt 116 US Dark Green
and Revell 80 Tan for the brown!
I used the colours i had at that time and haven't looked for the correct ones since i didn't had any refs to guide me!!
The safe path on the wing decals you mentioned was a pain in the @ss cause they broke down and i was trying to put them in the right place!
Anyway all the other small details you mentioned are indeed wrong!
The Guns wasn't drilled!
and the exhaust dirt is indeed too much!!
It didn't came out correctly when i tried to weather it!!
Anyway i'm glad you mentioned all of this and i'm also glad you like it in the Overall look!!!
Thanks again for posting!!!
Cheers!!!
