Hi Njaco,
Unfortunately I haven't found this post on it but you are right of "a camo where the old tail was painted on to simulate the bomber version to fool attacking aircraft".The "G" version of Ju-88 was modified and equipped with a new fin and a rudder which was a bit different in shape and bigger because it was taken from Ju 188 and the fuselage was of Ju 88R-2.But C version looked alsmost like A.The most visible difference was the nose of Ju 88C. I've found the pic I prepared for Pisis.
