So, somehow the material of the mill ball itself was used to give that enamel-looking effect?

Thanks, Al.

Vitro cage style cat's eye. I don't know if they go back as far as the 1950's. They were still being made in the late 1980's. Maybe 1990.

It's a keeper. Vitro hybrid cat's eye. LIkely 1950's. I count three colors. Two is "common". Three is less common.

2nd picture. #1 ... don't know #2: Asian ca'ts eye (or Mexican) #3 and #4, Vacor de Mexico. The group shots have a mixture. Lots of modern Asian or Mexican. Some of the 1960-ish Veiligglas wirepulls from Amsterdam. Maybe a few older American patches.

Top picture needs more views .... first glance looks like a Vitro Conqueror on the left and a Peltier Rainbo in the middle. The ribbon on the right is interesting.

You have hard ones!

Japanese?

With the salmon and blue I want it to be Peltier. But if that's just three ribbons then maybe MK?

After a few decent snowfalls, with a couple bordering on massive, our snow mounds should last awhile. It tickles me to look outside in April or May and still see snow.

oh decadent!

I'm with Al

That white ribbon looks totally pelty to me ... but the rest of it ... well, it made me afraid to comment

Maybe 1940's

I think I'd keep it with the Pelts.

The seam is the main thing I was looking at. My main guess was MK but then I tried to think of who else might have that kind of color striation and so I thought maybe Vitro.

Not sure. My first two guesses would be Marble King or Vitro.

Left to right in top photo: #1. Maybe Master. The long seam in the first photo holds me back. In the second photo I think I might be seeing a hint of a shorter V-shaped seam. #2. I think I'm seeing enough of the seams to make a Peltier Rainbo call. #3. Probably Akro Cork. More views could nail it down. #4. This might also turn out to be an Akro cork.

Champion? Alley? Jabo?

Modern Asian ... AKA Imperial

Then I'll go with slag. I wish it was purple!

Peltier Multicolor Rainbo. A nice National Line era marble (early 1930's).

1 Vitro 2. West Virginia Swirl 3. I'd like to hear more about that one ... is that lighter color white? Because it's looking pink or purple on my monitor

Vacor Serpent -- has made many a person hope for it to be Peltier https://www.billes-en-tete.com/detail.php?id=51
