Steve, in your work on this aircraft, did you encounter any information on the long range tanks installed on some models? From what I've found, there was a 250 US Gal tank in the bomb bay and a 134 US Gal tank in rear fuselage somewhere around the ventral gun position. Do you know if these were used in combat? It would seem that the bomb bay tank would preclude carrying much bomb load, if any, as it would weigh in at 1,500lbs and the fuselage tank might prevent the use of some of the rear guns? Just wondering.
