Hello
Tamiya's decals for Fröba's A/C is quite good. But enclosed profile of the tail should give some more color on the plane.(+ the werk.no as in Tamiya instuction)
In addition many A/C from 4/JG 77 had yellow wingtip on the top (not under).
I cant say for sure if Fröba's A/C had it but photos from his homebase (Herdla) show several planes with yellow on the top of the wing
The two victory marks on the tail was one Skua on 13 sept and one Blendheim on 20 oct. Both markings white with most likely RAF rundel on the top
Best
