Tomytec "Hamanasu" narrow-gauge railbus + tank wagon, 9mm 1:80, motor included

Description

This is from the Tomytec (Tomix) "Tetsu-kore" (railway collection) series of scale models. They are sold as static display models, and they separately sell the chassis to convert them into motorized model railways. The TM-07R is the motorized chassis that fits the railbus, and TT-03R is the metal wheels and couplers for the tank wagon. I am selling them all as a set.
The "Tetsu-Kore" narrow-gauge models are 1:80 scale, and run on 9mm track (same as N-gauge, OO9 and HOe). At 1:80 scale, it is between HOe (1:87) and OO9 (1:76) scale, so it should look OK with either HO-scale or OO-scale structures.
TheTM-07R has been tested, and it runs smoothly. 289357 has been opened once to inspect, but that's all.
