I apologize, but I am probably the last person on the forum that could identify different West Virginia swirls. 🤣
I get cross eyed sometimes when I try to tell them apart. 😵💫
I wonder if the yellow guy is a JABO. I've seen them come in weird yellow and brownish color combos.
The second guy (very nice colors) looks to me like maybe an older West Virginia swirl.
Interestingly enough, most of the pre-war Japanese marbles seem to be Nippon products, not Yasuda.
For example, Aiko seemed to say that she comes across far fewer pinch pontil transitionals than crease pontil transitionals.
As for the individual marbles, the first four look like more figure 8's.
The two slags at the end look like Japanese transitionals (the first looks like Nippon Special Glass Ball MFG Co product). The second one could be a Yasuda pinch pontil (since I can't see a big crease pontil).
Here's another guy (Yasuda pinch pontil) that I found a couple days ago in a large jar mostly full of opaque game marbles and older Japanese cat's eyes.
I think the hardest to find are the pinks/purples. (At least from my experience). But I think those colors were mainly made by the Nippon Special Glass Ball MFG co (all of my purples are crease pontils).
Aiko says if they have a long, spidery crease pontil (not a short pinch pontil) then they were made by another company. That company was the Nippon Special Glass Ball MFG Co
Quite a mouthful 😵💫
I found 6 of these guys yesterday (a personal record) near Pike Place market in Seattle! All are about 0.9" 🥳
I also found some smaller caged examples in a light Lavendar-ish blue/purple. One of them even has brown on it too!
