J Chein Ferris Wheel
Occasionally we get toys in. This time a clockwork ferris wheel by the J Chein company. The mainspring is broken.

The end of the spring is broken off and the sheet metal block that attaches it to the winding stem is off.

After heat treatment, the end of the spring can be reformed.
