Thank you all, for your kind words.
It was a bit of a guessing game when I painted the Cougar shell. I didn't have the decals at the time of painting, but it worked out well. I had to cut the side windows down and re-shape them to allow for the side decals and didn't know if I had allowed enough room, but I did.......
Also the penguin cougar Mk1 shell and wing is stunning work from Steve perfect fit.
