Set is 99% complete with all original minifigs and side build of the maintenance train and is in good clean condition. The only piece I could not find was one 2x1 red smooth-grill piece that went on edge of lower wing I've substituted the missing piece with two 2x1 red smooth bricks and the one red piece that I do still have will come with set it's probably not that uncommon so would likely not be that hard to find one. I've included photo of the missing piece and close up of lower wings opened showing substitute piece.

Box has some damage wear it was opened see photos.
