It works when you wind the spring. Made by Sanko Seisakusho in Katsushika, Japan. Katsushika Ward was once called the mecca of the toy industry, and even now, it is a workshop that continues to manufacture tin toys from parts to products, although on a small scale. My father kept it carefully. It is almost unused, but please refrain from purchasing if you are concerned about deterioration over time, amateur storage, or amateur inspection.
