Despite my best efforts I have been unable to locate reference to a Wireless Op/Air abbreviation addition. It Is Wop/AIR/S.E.A. The guy concerned was posted to RAF Mildenhall, not a Squadron, but has an Aircrew Europe medal. My puny guess is that it covers Special Equipment, but there I run out, Possibly 199 Squadron. Guy in question is Sgt F.C. Creasey. Any help appreciated.
