Per Model Railroad Forums, vintage Mantua  / Tyco items are of collector value and sought after. Here is a Mantua / Tyco READING  (Speed lettered) 2 Bay Ribbed-Side Hopper car # 65950 from the 1950's. The Mantua loop couplers & pin were removed in favor of added Kadee Knuckle couplers and a coal load was added. The bay doors open & close (see picture).The car is heavier than the usual later models and weighs 5 OZ. in box The trucks, wheels and Kadee couplers have rust weathering applied. The car had minimal run time and has been in storage. This is an exceptional undamaged car! The original box is long gone so it will be shipped via USPS Ground Advantage in an adopted marked up Lifelike box (see picture). All stored HO equipment is being liquidated.
