This is a game marble. Considered "solid color" thought it might have some variations in shade.
It is almost impossible to ID who made a game marble unless you have the actual package in which it was originally sold. Game marbles was a big industry which many manufacturers took part in.

This inspires me! I keep saying I want to make a very small run ... and I honestly keep thinking about it ... thought about it this past week ... am saving micropeewees for the purpose. But I guess I could also try to find one of these to buy because it looks so fun.
I was about to say I was unable to comment on gallery photos. But apparently a recent software fix changed that. I added one comment. I'll go have another look now.
