I'm embarking on a new project to depict a P-38 from the 39th FS, 35th FG in approx. mid-summer 1943. The type in question will be an F model, I think.

Can anyone tell me any external differences to look out for between the E, F,G and H models?

Also, I have collected quite an amount of ref material, but if anyone else can furnish me with more info on this outfit and its '38s, it's all useful and appreciated.

Thank you.
