The USAF Museum did much the same thing with the Memphis Belle. Stunning exhibit. My only tiny qualm is that though the plane has the markings, exact down to a wayward .50 shell casing in the nose, as seen in May 1943, she looks factory fresh. Clean, like the model I made as a kid. I mean, four radial engines and 25 combat missions don't leave a plane looking new. Also, the turbos should be dripping oil on museum goers.
Conservation and story telling leaves a lot of interesting decisions to be made.
