The dropping of atomic bombs from B-29's was a HUGE FACTOR in ending the war in the Pacific and I don't recall reading of any B29 missions in the European theater before VE day 7 May 1945 other than as a method of deception to make the Germans think they were being deployed in theater. 5 June 1944 B-29's flew from bases in India to bomb the rail yards in Bangkok in its first combat mission.
Therefore I would expect to see many other more deserving bombers to be represented in AH prior to the B29. Some specific examples to name but a few are:
German - HE-111, DO-17
British - Beaufighters, Wellington B, Halifax,
Italian - SM79, SM81, BR20,
Soviet - PE2, DB3, and IL4
