Now this is a surprise to me.  I know that the F6F was flown by the Brits, but I was unaware of any victories scored while in their use.

The FAA's Hellcat's operated in the North Atlantic, the Mediterranean, the Indian Ocean, and the Pacific aboard both Assault Carriers and Fleet Carriers. Although aerial combat encounters were limited with the FAA Hellcat, it still managed to account for 52 kills during the war.

Unfortunately for the Fleet Air Arm, none of its pilots achieved 'Ace' status while flying the Hellcat. The highest scoring FAA pilot was Sub-Lt. ET Wilson, of 1844 Squadron, with 4.83 kills. The top scoring Squadron, embarked upon the carrier HMS Indomitable, was 1844 Squadron with total kills of 32.5.

 How do you get .83 of a kill?
 I know that shared kills are worth 1/2 and in some cases aircraft distroyed on the ground can be considered as part or even a whole kill, but how do you get .83 of a kill?
