I would not count it out, Akro made some oxblood that was more transparent than opaque CharlieT--a good observation for sure!
Nice images mccracken,
The fact that @Alan has a few like this makes me wonder.
I am inspecting the damage on the marble, this usually will determine old vs newer. Newer glass in my experience is softer and more prone to little white hit marks.
Jabo is a good example of these little whit hit marks. @Nantucketdink has a very good handle on Jabo marbles, he could clear this up for sure.
There appear to be striated scratches not common to game play but more often found in a marble from a dig-site. @Steph may be right on the older WVS idea and @cheese and @Ric both have been on the digs and may offer an opinion.
I see why mccracken though that it may be a Peltālots of bubbles. Experimetal marbles were not always cooked like production types and this may explain the ābubbliciousā nature of this one.
I am leaning towards a vintage dug marble, it may be from any number of dig sites imho. If @Fire1981 did not recognize it, then I doubt that it is a Pelt.
We cannot ID them allābut we sure as heck can try.
Thanks all!!
MarbleāOn!!
