Which squadron uses the BF-109E-4 during Battle of Britain. I have here the 1/48 Hasegawa BF-109E-4/7 and it only had markings which I don't know if applicable to the ones used in Battle of Britain.

These are the markings included:
Maj Helmut Wick - Oct. 1940 Belgium
Oblth. Helmut Wick - Sept. 1940 France

Which one should I use?

Hi Shonen, Helmut Wick flew throughout the Battle of Britain with JG2 and later JG27 until his death at the end of November 1940. Both sets of decals would be appropriate for the BoB. It would be worth doing a search on the net as the camouflage changed on his 109Es as the battle progressed.

Thanks man! Actually the kit colors is good enough for me.
