A little blurry but those first two in Post #3 are the angles I wanted to see.
Sorry to be a hard-ass.
I'm certain that they were made on a Rainbo machine.
Here's the thing which is making me hold back. The ribbons don't appear to have the typical Peltier Rainbo pattern.
That makes me want the marble to turn out to be a Kokomo. The Kokomo Opalescent Glass Company bought some marble making machines from Peltier and used them for a short while. They did not make very many marbles. So going by the numbers, it's unlikely that it is a Kokomo.
Numerically, the odds are far better that a rainbo-looking marble will be a Peltier.
But I'm just not seeing the ribbon pattern for Peltier.
BUT ... one more big BUT ... if you identify something as Kokomo on eBay, people won't like that. There will be some curious and then possibly angry person who will want to know why you said Kokomo. So don't say Kokomo unless you get a solid consensus that that's what it is.
Did that make any sense?
