I’m working up a B-29 Superfort in the Korean “conflict” and can’t seem to find any decent pictures of a B-29 with the gloss black undersides. Anybody have any good reference suggestions for this? Are the upper surfaces a nice, shiny aluminum, or were they painted with a silver laquer for corrosion prevention, like the F-51’s were? Any info would help. Thanks!

couple of things to look at.
Here is a photo of a Korean B-29 sitting in Japan after 60 missions. I can see tonal variations and enough surface detail to convince me that it is natural metal. Photo is from Bill Yenne’s History of the U S Air Force.

Wooo Baby! Love that nose-art!
