Unless I am mistaken, this is the B-26 modified to test the
tandem landing gear design for the B-47.

"The only other Marauder variant was the single "XB-26H",
named the "Middle River Stump Jumper", a test article
converted from a B-26G to evaluate the "bicycle" tandem
landing gear scheme for the Boeing XB-47 and Martin XB-48
bombers."

I assume the fore and aft bars added to the fuselage are to correct some
structural deficiency associated with carrying the 4th wheel?
