Thanks much. There is indeed an oval window on the sprue and shown (but not mentioned) in the instructions. So some version of the model must have been intended for FAA use. You're right about the Italeri kit and I would have bought it if I would have known about it. (Got their rebox of the AMT P-40 and it has splendid decals for several services.) As for the decals, we'll make do I think. I'm thinking this plane might have flown for Coastal Command when they started putting on the screws first over the Bay of Biscay and then German exits after the U-boats left France, or hitting German shipping in that nasty little war going on east of the Channel. (Someday it will join an Academy B-17 MKI - which is the Italeri version of an Academy 1/72 B-17B I just bought - which is too pretty not to build even if it left something to be desired as a bomber.) I know there some internal changes made but it doesn't sound major.
Researching this has been great fun. I've got a load of Pacific Theater stuff and let's face it - war is the enemy of art. The Japanese planes are neat, but the US stuff, whether it flew or floated, is all blue of some type. (Some of the very early war stuff excepted.) One can get too much blue. The US put SBDs on some their U-Boat hunters and they sport a very nice white/gray scheme. (Could of done that with the TBM too, but the FAA scheme is even better.) And from the sounds of it, the Atlantic based CVEs and aircraft were kept very busy. I'm definitely going to send my Laffey to the Atlantic. Better colors. More to do on leave. Pity there's no USS Bogue to build.
