This is a vintage 2nd class passenger coach by Marklin for their HO gauge 3-rail systems. Model number 4002. As can be seen, this model will require a bit of cosmetic care to bring it back to its full glory. The roof is in poor condition but there are no green livery, although worn, is fairly chip free. The body appears complete but it is untested. I think there should be two small suspension springs to the underside which are missing.
