I am attempting to create a service history record for B-24 Liberator aircraft in the 8th Air Force. Can anybody suggest where I can find records of aircraft assignments & transfers. Would I want to obtain Base Air Depot records? I have the Individual Aircraft Record Cards (IARCs) but these only show stateside assignments. I am looking for the assignments within the 8th Air Force. Any help will be greatly appreciated. I should mention that I have a copy of Heavy Bombers of the Mighty Eighth by Andrews & Adams. I'm trying to put specific dates on when B-24s were assigned to units.
