That's why I was scratching my head.
1. I know Sara's collection is old. I think a couple of newer marbles may have slipped in but it was overwhelmingly a vintage lot.
2. I did get a little bit of a Jabo feel, but see 1.
3. The marble on the right made me think of both Akro and Peltier depending on the view.
In View 2, is that a seam between two red ribbons?
Is the green and red one just green and red? Or does it have white also?
Could you specially show us the ends of the patches?
My initial guesses are that they're Akro, but still
