Eidai model wind up shops race Cars 1968-1969

1968 -1969 eidai model wind up race cars , they have been built pretty good , no decals and the keys are also missing to wind them up it's just a little square key , I'm not sure what would possibly shops be missing there are a couple of loose parts in the box , the model pictured on the box is not in the box , these 4 cars were packaged in the box. They seem to be in good shape the deck lids open on most of them and the wind up mechanisms are in the vehicles , one of the wheels are loose because a little piece broke off that holds it In Place but that piece is in the box
