I'd say no to the Spitfire mk Ib and Mk IIb. They were failed attempts to get cannons on Spitfires and jammed so badly trhe squadrons so equipped wetn back to Mk Ia and Mk IIa Spits. In AH they wouldn't jam and would be used almost exclusively over the Mk Ia and Mk IIa Spitfires.
+1 There must've been thousands of BoB planes produced, and we have only 6!
I could care less about arena use. Moreover, gun jams are not the only malfunction that we leave out of AH, so it's not a big deal...The point is that we're missing aircraft that saw action in the Battle of Britain, and I'd like to have them.
...110C-4 (not the /b variant with the upgraded engines)...
Wow, you guys need help.
