Yes they did--very few. Try to find a 9/16" corkscrew and see how rare the peewees are.
I wish that your was one--really I do. The colors are right for sure--the structure is wrong.
Yours is a WVS of some sort imho.-it just wanted to be a "Better Marble"--😁.
I want them all to be Akro--sadley, there were other makers as well--good thing for all of us or it would get a bit boring.
I apreciate all opinions and welcome them all.
Marble--On!!
