The 'Middle River Stump Jumper', a modified B-26 Marauder,
which was used by Martin as a test-bed for developing the bicycle undercarriage concept.

from 'Air Force Legends' #201 'Martin XB-51'


cheers,
Robin.

Yes, it was used to test the bicycle landing gear for the Martin XB-48 - the unsuccessful contender against the B-47.
 
Does anyone know the colors this flew in? In some pictures the under surfaces looks to be natural metal while the upper surfaces look to be a deep green, but I've only seen black and white shots of it.

Thanks,
Mike
 
Pretty sure the fuselage was OD and the bottom of the wings and engine nacelles were natural metal.
Here are some NARA II RG342FH photos I found last week during a visit.

Wow, nice pics. I never realized they had to stiffen the fuselage so much, but it makes sense given the change in loads.
