Mark,
I have seen two B-58s up close. One I remember distinctly had its landing gear painted silver. The wheel wells were also silver.
The exterior of the aircraft was natural metal, except for the anti-glare panel.
The cockpit was a medium gray with black instrument/dial panels. I think the ejection seats were black. I only saw the pilots compartment and did not see the other two.
I think the other B-58 had the gear wells painted white. The landing gear was the same, that is silver paint. I did not see the cockpit of the second aircraft (classified at the time).
Sometime in the 1960s there was a Tech order for the painting of B-58s in Southeast Asian camoflage, like the B-52s with black undersides. Does anybody out there know if any B-58s were in fact painted in Viet Nam Camo? rangerj
