This is a rare Right-of-Way Ajin O Brass NKP Berkshire 2-8-4 steam engine with tender. It is number 5 of 110 made. It is clean and dust free. The front light and one tender light do not work. It will run on O31 track. I did test it and it does run good. Has sound and smoke.   If run much I would oil it first.  The locomotive is in very good condition with a C-6 grade. It is a 1:48 scale model made of brass and is powered by AC. The locomotive is pre-built and ready to use. It features a tender and is designed for use on a 3-rail-2-conductor rail system. The corporate roadname is Nickel Plate and it was manufactured in Korea. Please refer tonpictures before bidding snd contact me with any questions, thanks.
