Thank you, Alan.
Butt jokes aside, I was looking at the coincidental and seeming purposeful placement of the so-called pigtails in essentially the same place on both of the marbles I was trying to identify.
I was thinking of the "pigtails" as "insets" because they look to be quite distinct from the glass in the rest of the marble. Since the glass of the pigtails/insets is so different from the rest of the marble, this doesn't look to me like a shearing error.
And, yes, I want people to look at the glass. Both in the pigtails and in the rest of the marble. Kris started talking about that, and allowed me to point out one difference between my mibs and the stereotypical Jabo.
But once again, the abstract fact that Jabos can have U-shaped swirls and wrinkled glass seems to trump the discussion. If my marble looks so much like a Jabo, I want to see the Jabo it looks like! So far all the Jabos that I know are Jabos suffer in a side-by-side comparison to these. I'm open-minded, and I want to know the truth, and if these are Jabos, okay, but if they are someone should be able to produce a picture that really looks like them. Not just words about shared traits. After all, even Akros and CACs and Pelts can all have U-shaped swirls and 'butt cracks'.
So, back now to my real specific tangible mibs:
The swirls in my two mibs are simple but very rich and bold.
Further, the 'cheeks' on the first marble make it seem as if the glass was in a unique state of viscosity as it was formed into the basic marble shape. Like folds of taffy or really thick honey. Then after the glass was folded onto itself, it does not look like it went through a traditional rounding process.
I don't know how the machinery works to round out machine-made marbles, but whatever the process is, I don't think it looks like my two swirls went through it. Do you see what I mean?
I ask you very seriously. Since the rest of the thread has devolved into giddy humor, I would like to hear what you think about what you see in the glass in the pix I've posted so far.
I've held onto these marbles for awhile, waiting for some insight, and I'll keep waiting because I think that some expert is going to dig up something that looks just like these at some very old factory site, and I don't want to be crying and saying, "I knew they were special and I wish I had kept them!".
Thanks again,
Steph
