You've got to realize that during the 50's and early 60's millions of Cat Eyes were produced, by both American manufacturers and Japanese manufacturers. Clear glass almost certainly means American made. Nearly all the Japanese marbles used recycled glass for the base which resulted in a transparent green base. Unless there is something that stands out, cats are really hard to ID. I'd venture a *guess* that this one may be Marble King. But that's just a guess.
Sometimes though you find types that are easy to ID. These are all Vitro hybrids. Very collectible.
