Thank you to Lyric1 for finding me the info for this skin, which was originally skinned by Fencer in 2008.
"Dirty Dora" was the B-25C flown by Lt. Vic Tatelman of the 499th Bomb Squadron, 345th Bomb Group. The squadron arrived in New Guinea in late 1942 and were initially used to air drop supplies to front line troops. Later their aircraft were modified with a set of eight nose guns and used to bomb and straff Japanese airfields, shipping and other installations at very low level with bombs and their nose mounted guns. The 499th were named the "Bats out of Hell" squadron and had their aircrafts' noses painted with a large blue bat.
Having completed his tour of duty nd been promoted to Captain Tatelman was assigned to a course in radar countermeasures in Washington before being sent back to New Guinea as part of General MacArthur's Intelligence staff. Here he had another B-25D dubbed "Dirty Dora II" outfitted it with radar homing equipment and used it to locate and destroy 20 enemy early warning radars.
