WHen I was in the UOTC, the RA Wing PSI wore two sets of jump wings, one of which was the Paras as he was P Co trained and he another silver looking emblem which looked suspiciously close to US jump wings. He said they were they were Dutch ones.
It used to be customary to hand out host jump wings to qualified personnel from other NATO countries on airborne joint excercises. Usually the requirement was to make two jumps with the host - often this would be the aircraft jump at the start of the excercise, then often they would put up a balloon as part of the endex-hangover recovery day to get in the other. I ended up with wings from four other NATO countries.
It was not considered good form to wear any of them though, but things might have changed.
