Chinese Nodders Playing Goh

I think that those are goh things in their hands, but not sure. This arrived today. i won them in an online auction. The are completely intact, but i had to jerry rig one of the wires. When do you think these were made? I dont think theyre very old, but probably early 20th c. ?? i'm not ever sure they were made in China. They could be Samson. I remember my great grandmemere had two of these in her front parlor and us kids were fascinated by them.
