Buzzsaw - You're mixing something here. The export thingy was the
Bf 109 E-3a (in which the
a denotes the export use). The Romanians received the same type as did the Japanese (the latter for tests). I have the full Bf 109 E manual compendium from Luftfahrtarchiv Hafner (reproduced originals) and the DB 601Aa is listed as engine type.
BTW you accuse Kurfürst of " a viewpoint". If I were you I'd be very quiet since you obviously represent the other side of that particular medal.
