Yes the earliest production Hellcats were built before the three color scheme came along in mid 1943. So they were painted in the early war Blue Gray over Light Gray.
In 1/48, aside from Eduard, there are also F6F kits by Hasegawa, Hobbyboss, and the old Otaki kit that has been reboxed by AMT, Airfix, ARII, and who knows who else… plus the old Fujimi and Monogram kits.
This is the Otaki kit that I built about 15 years ago…
