Feedback from the fleet had not been very favourable to the F4F-4, so Eastern produced a variant that reverted to the four 0.50-inch guns of the F4F-3 under the designation of FM-1. No four-gun variants of the F4F-4 aircraft were built by Grumman. It is quite possible that some MAP paints were sent to Eastern Aircraft before the production line then switched to ANA equivalents for both the FM-1 and TBM-1C for British service. Close - but not quite correct. Avenger/Tarpon I aircraft were designated TBF-1B (for British) and were very similar to the TBF-1 for the US Navy but had the domed observation window on each side in the lower fuselage. All these aircraft (British and American) had what is best described as a three-seat cockpit - pilot, radio-operator behind him in a proper seat, and gunner in the turret. Their forward-firing armament was a single 0.30 on the starboard side of the cowl firing through the propellor. The Avenger II was the British designation for the Eastern TBM-1C (equivalent to the Grumman TBF-1C) which moved the radio operator to a position in the lower fuselage immediately behind the bomb bay and filled the space in the cockpit with radio equipment. The forward-firing armament was changed to two 0.50-inch guns, one in each wing. The British did not like the new crew arrangement, so Blackburn rebuilt the second cockpit position to essentially duplicate the original arrangement in the TBF-1. Nevertheless, there were quite a few other detail differences between the TBF-1 and the TBM-1C, both external and internal, Furthermore, Britain did not receive any TBF-1C aircraft, so the different mark numbers related specifically to actual physical differences, not different manufacturers. Vought built all Corsair I and II aircraft but the two types are quite different. The Corsair I is the original "birdcage" type while the Corsair II has the later bubble canopy. Within the two marks there are many variations, but the two designations exist to distinguish two quite different models. On a side note - the Corsair III, built by Brewster, throws up a puzzle. The FAA never deployed Corsair III's operationally but used them almost exclusively for training British crews in the USA. One reason usually given for this was that the gun mountings in the folding wing panels of Brewster-built machines were too weak to allow continuous firing. The odd thing is that most of the folding wing panels for the later Vought-production Corsairs were sub-contracted to Brewster, and Blackburn (responsible for modifications to British standards) makes no mention in its records of having to strengthen the gun mounts of Vought-built machines! I apologise for wandering off-topic - I could not see where else to put this information. Maurice Thanks Maurice, I found a reference (can’t find it now of course) that the first MkVs were in MAP colours and made the assumption built by Grumman (possibly built by Eastern but under Grumman guidance) and that the narrow range of serials covered the particular aircraft I was researching JV384. I’ll see if I can dig out the reference.. 2 Link to comment Share on other sites More sharing options...
