Lt E.G. Wilkinson

I am presently researching Lt Wilkinson's service career for his family here in New Zealand. *I am aware that he served with both the RNAS and RAF during 1918-19. *I am also aware that he served with 12 and 13 (Naval) Squadrons in France. *With his British War Medal and Victory Medal was a length of ribbon for Belgium's Croix de Guerre. *I am hoping that someone maybe able to shed some light as to whether he was awarded a C de G or whether any other information is around on Lt Wilkinson.
Regards, Terry
