These cars were built to ship live poultry which was kept in 120 coops.  Hinged trapdoors in the car roof were for access to the water tank and also for additional ventilation during the hot weather.  The coops were stored on shelves in the screened area.  The attendant lived in the enclosed area above a large feed bin.  This should be painted green and white.  Please specify your choice of Hi-Rail or scale trucks and couplers.
