Hi, Gerhard:
The F3F was a biplane withdrawn from Navy service by the end of 1941, so it wasn't being used in 1942 at Coral Sea.
However, if the "3" is a typo, and you mean F4F, then it should be an F4F-3 during Coral Sea. The F4F-4 had replaced the -3's by Midway.
So, if you plan a Wildcat, it should be the F4F-3 variant here, for Coral Sea.
Otherwise, you can put an F4F-4 into the Midway GB.
I hope you can participate in one or the other GB with your Wildcat!
