Jerry, Yours seems more like a blue version of a skunk, which is four white ribbons on black - a Rainbo. Paul's looks like an earlier six-ribbon NLR type.
I have always liked transparent red base glass and I would really like to see a wide variety of examples, so please, show them if you have them.
Thank You!
It's hard for me to see the true colors in your pics, I think. It looks more green than Jeeper's to me, but if the colors and glass in your marble look like Jeeper's, I'd go with Peltier, because I am confident his is one.
Vitrolite was structural glass. A number of WV marble manufacturers used scraps for base glass occasionally. The milky green you're showing glows.
Your marble may well be Alley, I'm just not sure which site is most likely. They used similar glass at both.
