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.
Slightly digressing here, but I've seen the then 55th SOS brought their MH-60G to Mildenhall for the 98 Air Fete for the first time. The aircraft commander wore two sets of wings on his brevet patch, one of which was the silver USAF and USN gold wings. Turned out he entered the Navy, flew for a few years on the SH-60B and then transferred to the USAF.
Funnily enough I have come across RAF SH pilots that had transferred either from the AAC or FAA, but they don't appear to wear both sets of wings they've achieved on their flight suits? I am assuming its the regs that says that.
