For The Empire Strikes Back, ILM used MPC model kits for the closed wing X-Wings in the scene where the Rebel Transport escapes Hoth. They were also employed throughout Empire and Jedi in other areas as well. Surviving examples are “all over the place” in comparison to the “established” hero liveries of the models made for the first film, so I decided to have some fun and just paint them as I wished. So these are NOT specific to any ILM painted examples, and I sleep at night just fine 😉
