I have just received that little loco, impulse buy on the bay in Germany. It needs a total restoration which is not a problem, it is a two rail model. The pictures where bad quality and I was thinking maybe made in Japan in the fifties but after receiving it... I do not know.
Classic DC motor from the fifties, heavy piece all made of brass, very well done and smooth running. Wheels are steel models. One thing that look strange for me is the cab windows, original or not ? All of this is in need of a total rebuilt and will be a nice project for the upcoming weeks.
