There are likely not too many US steam locos that have been active for 27 years and have never been captured for RP, this is an exception. #9 was built for the US Navy by Porter as a tank engine in 1942. She's pretty hefty as far as 0-4-0's go: weighs about 50 tons, has 45" drivers, 16x24" cylinders, and makes about 21,500 lbs. of tractive effort. She was returned to service for the annual Southeast Old Threshers reunion in 1982 looking like a completely new loco. She was converted from oil to coal, and her tank was replaced by a 2000 gal. capacity tender. Other modifications included removal of the second sand dome, major changes to the cab, and oddly the addition of a diesel-like mechanical bell under the cab.
