If correct, both pictures hereunder, shot in Antwerp should be taken after the Air strike against Erla Werk Antwerpen/Mortsel. Planes could also be of the Industrie Schutz Staffel stationed at Deurne Airport, reporting IIRC to JG 1 stationed at Woensdrecht
Could be interesting as a staffelabzeichen (?) is not known to me.
