Air Force wings

[Alain Conradi]

Dear all, on top an obsolete RAF parawing, second the current one. But the third one is on black, also RAF parawing? And what about the fourth one, also on black but completely different style. Appreciate your help.
Cheers,
Alain

The bottom black is WW2 mate. I’ve had a few pairs and have one left currently. I’ve read SOE, foreign use and just a variant.
AFAIK there’s no conclusive reply pal.
