The 366th FG did not have any color markings except the standard ETO markings,white on camo P-47's and black on the natural metal P-47's.
As stated above.
But towards the end of the war these stripes were removed .
The front cowling color was removed on most P-47 and tail stripes depended on the P-47 .
There is a book on this Group printed by the 366 FG association but not sure if it is still around,try here:
