Vintage HO scale Penn Central end-cab diesel switcher #9165 (SW7 type), diecast frame with brass wheels and Kadee knuckle couplers at both ends. Modeler-added yellow wire handrails and a red cab-roof light lens. No maker stamp is visible on the underside, so it is listed without a brand attribution. Track-tested by the seller and runs - moves freely on the track. Dusty from storage but complete; see photos for condition.
