Wojtek mate, I owe you an apology! :
(From 'German aircraft interiors 1939-1945' by Kenneth A. Merrick):
'...Another version of the G-10 was an interim model known as the Bf 109G-10/AS. This fighter, powered by the DB 605 AS engine, also appeared in November 1944 but was considered only a stop-gap variant until the production of DB 605D engines became more constant. Relatively few of the fighter, characterized by their slightly different cowlings and forward fueslage contours, were manufactured...'
(Photo of Bf 109G-10/AS W.Nr 150816 Black 4 of 6/ JG51 shows the bulge aft of the propeller (almost directly below the front exhaust) is non existant on G-10/AS aircraft, but very apparent on standard G-10's)
Also mentioned:
'The Bf 109G-10 series employed several different rudders in combination with two different tail wheel legs.' (Your white 44, and all three G-10/U-4's exported to the US had: ) 'type 8-009.320 rudder assembly, characterized by fully adjustable Flettner trim tab located about mid way along trailing edge and supplemented by two additional tabs which were only adjustable on the ground'
