Indeed, Diablo, the first picture you posted is a D5, with the longer, pointy wingtips. The second one should be a B (or maybe even an A?), and yes, it's a Spanish camo. The tipical Stuka wingtip is the "clipped" one, even AH D3 has it.
I never saw pictures of the navalized Ju87, thanks for posting them (lexicon der wehrmacht, very nice site, too bad it's in German only!
)
EDIT: Yes, the "Spanish" one is an A, as ridley noted, the wheel spats are in their original shape.
