In general, aircraft involved would be, for UK: Short Sunderlands, B-24 LIberators (someday I'm going to do Monograms 1/48 B-24D in RAF Coastal Command colors), Fairy Swordfish, maybe Seafires and Sea Hurricanes
For Germany FW-200 Condor, Arado-196, BV-138
For the US, TBF Avenger and F4F Wildcat
You'd have to do a little research for particular marks for particular times of the conflict. What I mentiioned were just off the top of my head.
I'm doing a Sunderland, myself, for an Anti-Submarine campaign that starts in 2010 as well.
