HO scale caboose body kit suitable for modeling cabooses of GN Nos. X31-X50. For Nos. X31-X40, use with Moloco 1501; for Nos. X41-X50, use with Moloco 1502. Use an Atlas extended vision caboose to supply the underframe and end railings. Moloco offers appropriate end gates and battery boxes for this prototype. Other caboose detail parts are available in my store, such as smokejacks, toilet vents and brake details.
