This is an assembly kit from JOKOSHA that the seller assembled and painted. Please forgive any imperfections in the details, as it was made by an amateur. It has been stored for a long time. I have confirmed that it runs, but when running, there is a slight pause in the electrical current, and the motor and gears don't mesh smoothly. However, it starts running stably after increasing the voltage. Those who prioritize running performance may find it somewhat unsatisfactory. There are many attractive narrow-gauge steam locomotives, such as the Baldwin of Kiso Forestry, as well as Koppels and Shay geared locomotives. This Rio Grande saddle tank is, along with Porter locomotives, one of the cute types, I think. It's heartwarming just to look at it. Please purchase with the understanding that it is being sold as-is.
