I want to start modeling a B-57 that was used for radar evaluation flights (PREP flights) by the US Air Force during the 50’s and 60’s, but I haven’t found any color pictures. The best I can make out is the aircraft were bare metal with bright orange trim. There is another radar eval aircraft at the SAC museum–a B-29TB used by the same unit, by the site doesn’t have any photos on its site…any help would be greatly appreciated!
