Hi gibsonfndr,
Thanks to expose this question better than i could about those two strange JG 301 Fw 190 with inverted fuselage bands visible in Sq Signal Walk Around... Which i think could also show airplanes from JG 5 ?
Note that except if Kjetil Aakra come here, another good place to ask this same question could be
WWII Air War over the North :
