I haven't been paying attention to the project but I think I'm caught up. I've been assuming I'll have all so it's difficult to just pick some out of the set. I have two planes to choose from (not the p-51 which I already have) and I'm not sure which to pick. I'd like to have a rounded collection (I hope that's the word I'm looking for) so maybe the spitfire and dora? That'll leave me with American, British and German.
I'm very casual and my knowledge regarding them are mostly based on documentaries, reputation and child like fascination on how awesome they look.
