18 sections Aurora HO scale Model Motoring 9" Radius Curve Track No. 1519. They are in okay condition. 4 of them have cracked off screw holes. 1 has no screw hole? There are individual (sort of) photos of each of these. Some have red marks which were to prove ownership. They do not have pins or rods to connect them and they all need a sanding or cleaning. Please look carefully and ask questions or request more photos as I do not accept returns
