Okay, time to do some updates. I've been researching and studying interior colors for this aircraft. Thank you George for your help, much appreciated. One of the things
I came across was an article written by Martin Waligorski called, "Interior Colours of US Aircraft, 1941-45." This can be found on (
www.ipmsstockholm.org/magazine/2004/02/stuff_eng_interior_colours_us_part2.htm).
The section for B-17's says that the early B-17s had overall Zinc Chromate Yellow interiors, Bronze Green cockpits and navigator's stations, and Aluminium lacquer bomb bays. The general rule for F and G models was Bronze Green in the nose section containing the bombardier and navigator, the cockpit area including the pilots, top gunner/engineer, and radio room. Anti-glare was Olive Drab.
The inner fuselage sides in the nose, cockpit and radio room were covered with green canvas padding. The green in the photos I've seen look to be a kind of olive drab almost gray green colour. The Cabin floor was made of varnished plywood and high traffic areas were covered with black rubber mats for anti-skid purposes in the waist gun, radio room and top turret areas. The floor in the pilot/navigator cabin was left in natural metal. Pilot and navigator seats were most likely bronze green.
Aft of the radio room, early production aircraft were painted Zinc Chromate Yellow but later versions were often bare metal with Zinc Chromate Yellow or Zinc Chromate Green bulkheads and longerons. In photos presented in the article, I noted that both longerons and stringers were painted Zinc Chromate Green. Other items noted from the photo provided was the supports for walk areas and brackets for supporting equipment were also Zinc Chromate Green.
Prevailing Colour inside the gun turrets appears to be a Dull Dark Green with later models also using flat black.
Bomb bays and bomb bay doors were unpainted. Wheel wells are believed to be interior green.
More to follow as I continue my research.
