Well if we want to talk kills to amount of Hawks 75's and who was best with it, it would definitely be another American/Finnish plane as they saw the greatest success with it. 41 or so planes from Norway and France via Germany, achieving an un-bolstered 190 kills? vs 285-400 planes of the French and 230 kills and as you say the French inflated their kills.
The French have their own planes that need representation.
Like I said, I'm not hung up on who built what but who flew what and how much action they saw. By my guestimate, the artwork for the Hawk is roughly 75% done with the P-40C vs. 0% of the domestic French fighters. And as French don't have any representation in AH's unit listing yet, Hawk would be a great way to get there with something that isn't as rescource intensive as a completely new aircraft. Hawk was the aircraft that had the most "battle value" of the planes French fielded in BoF. For example, as Finns soon found out, the Morane Saulnier was a nightmare to maintain and the 20mm Hispano HS404 was complete piece of garbage, it had no reliability to speak of. Hispano evolved into a great 20mm cannon but HS404 wasn't that yet. Hawk was rugged, reliable and relatively simple to maintain. These things aren't important in AH but those are part of the reason why Hawk was the best fighter what French had during BoF.
One author's view on the issue:
WMaker... Just for <G>'s which version of the Mohawk are you espousing, Keeping in mind that the later two never made it to France, 1 which could out turn and out fight the Ki-43, or the 900hp A-1... transparent? Also what are your thoughts on the Prototype Model 75B related to the B-239?
Only four 1200hp Cyclone-equipped Hawk75A-4 got to France before the armstice, so the natural choise would be A-3. The planes differed very little overall. There were small differences with armament (4 or 6 guns) and engine subvariants. They all were powerred with Twin Wasps from A-1 to A-3. The biggest performance difference would come from the fuel. 100 octane fuel made it possible to use Twin Wasp's wep-setting which would give 1200hp for 5mins on the deck instead of the 1050hp mil (see the chart I posted). I have no certain knowledge but I remember reading that 100 octane fuel never got to the Hawk units during BoF.
