The Microscale sheet is 48-265. It says the "Witch" is Sand 30279 (modern FSN match) and gray 36473 lowers. AAF serial # 11840 letter "P" Serial # and letter are black.
I also have a Monogram Promodeler sheet done by Detail & Scale, it says 31575 uppers, 36173 (?) lowers. Barless, yellow surrounds on white stars on blue circles, which are not supplied. 98th bomb group, 343rd bomb squadron, 9th AF.
The colors of the "Witch" figures clothing are red on the micro and blacks and grays on the pro. Other differences as to size of the serial #, etc..
I'm for the promodeler, as microscale is noted for errors.
Given that the national insignia were changing, and the op tempo to get ready for Ploesti, all sorts of departures from the "official" regs can be expected.
