Also, for what it's worth, I have a 1907 article mentioning Japanese marbles. But it's a very racist. I don't even like to share it. No company was mentioned. The marbles would probably have been handmade.
Also, the marbles in the machine in this 1929 ad looked Japanese to me. But it's a very small photo and no information to go on besides the ad date. There were similar American marbles made, but not in 1929 as far as I know.
My first thought was Pelt NLR.
Al is giving me second thoughts.
I'll have to dig out the translucent Zebra that Mike Barton gave me and see how close it is. Can't remember right now and have to run to work now.
