It's a ribbon Latt, two ribbons in different colors. Nice pattern. Not understanding the controversy other than the fact you don't see them around too often. Nice looking marble
I'm not convinced "solid core with high transparency" gets the same google results as a jelly core marble? Love that marble though Alan, is it a William Murray
Could be what I'm seeing as the amber/gray/ivory part in your marble is actually clear ? Here area a couple oxblood patches with similar amber/gray/ivory and a bit of clear (of course not as swirly). Nice marble and you might be correct the alien spaceship landed somewhere in between and I agree it's usually seen with blue or green
I'd go with Akro based on pic 4. Bold ox with the opaque white in that view. The amber/gray/ivory I think is part of the oxblood just getting started or ending
I'd go with Pelt top right in post #12, and maybe post #9. Rest look like Marble King maybe (or something other than Pelt or Akro)? Just my guess, and of course I haven't seen them all
If you mean 3rd edition, plate 338 is a slightly different angle. not much, but same marble (just happened to have the book beside me and got to flipping through the pages).
So is it safe to say nobody around here has examples of these in original packaging? And the two color opaque handgathered examples as shown are the only type this company made (or would it make sense they made slags, and others etc...)
