You know, I have heard of google. Even used it once or twice. However I valued the opinion of industry experts over copious random internet babble, and chose the direct route. Is it not what these fora are for?
Anyway - thanks for the link.
Perhaps I should expand on the story a little and see if this explains better why I was asking on here.
The vessel he was on (Nairana) was on Russian escort duty in 1944 (I think) and several aircraft types were mentioned on their inventory. American types included. However I didn't see Corsairs mentioned in the list, so I was presuming they were from a different vessel - but possibly not...
Also, I don't recall seeing before what I previously referred to as RAF roundels on ship-borne (i.e. FAA) aircraft. By that I mean overall camouflage paint scheme with roundels which include the white and yellow bands. This is why I thought they were RAF.
