(First of all, sorry for doubleposting of sorts, even if separated with several hours)
Here's the first of the Naixoterk's previously-unpublished works - Royal Navy Grumman Martlet (F4F Wildcat)
-Martlet Mk.I was a designation of the 100 G-36A aircraft (85 actually delivered) originally built for France (and Belgium?) and diverted to Great Britain after the blitzkrieg of Spring 1940. They had French equipment and armament, nine-cylinder, single-row R-1820-G205A radial engine and non-folding wings (which limited them to land-based operations).
-Martlet Mk.II was a designation of the G-36B aircraft ordered from the beginning by the Royal Navy. They had Pratt & Whitney R-1830-S3C4-G engines, stronger (than US models) armor and self-sealing tanks, as well as folding wings which allowed them to actually perform carrierborne service (including on the first escort carrier, the HMS Audacity).
-Martlet Mk.III were 30 F4F-3A aircraft from the Greek order of 1940-1941 that were diverted to North Africa after fall of Greece.
-Martlet Mk.IV were F4F-4 aircraft with some British-specific changes, most importantly with Wright R-1820-40B Cyclone engine. 220 were made for RN.
-Wildcat Mk.V (initially briefly Martlet Mk.V, before it was decided to use US names on imported planes instead) were FM-1 aircraft, 312 of which were made for RN.
-Wildcat Mk.VI were FM-2 aircraft, 370 of which were delivered to RN.
Great Britain, Grumman Martlet (F4F Wildcat)
Also, the never-were (or more precisely: never-delivered) Grumman Wildcats were added here:
