Thank you for that drawing and technical description John, it was driven like a snowblower! I didn't know that drawing existed, now I don't have to imagine how it must have been driven. Unfortunately now I have no idea how half seem to be right and half left again other than the two operating opposing each other theory mentioned above. Any drawings or technical data recorded in that regard?

I don't have a pic on file. I'm not sure where the marble is but I'm sure I have it. Super busy right now but I'll try to dig it out in the next few days.

I think I saw that drawing wrong. The spinner cup is sitting on the gear, not on the end of that angled rod coming up from the lower right. I was thinking that was what was driving the cup one way or the other but maybe not? If not, then what I had envisioned is probably not possible. But still, I think the cup went one way, then reversed, and back and forth all day in order for there to be an equal amount of left and right twists plus ones that are messed up. I came to that conclusion years ago when I found a corkscrew that switched direction dead center and went from right twist to left halfway through the marble. Could be wrong.

You know how so many Akro corks are what we call "messed up corks"? I assumed that the spinner cup was gear driven, a simple mechanism with a round pinion gear on the spinner cup shaft with a long bar with teeth on it that pushed out one way, then pulled in, then pushed out, spinning the cup both ways, like the long rods that connect one wheel to another on a steam locomotive, back and forth as the wheel goes round. If that was the case, the spinner cup would spin one direction, then reverse to the other direction an equal amount of time. A "messed up" cork would be one that hit the cup as it changed direction. Just my theory and the way I had it pictured in my mind.

Thanks Chad!

Heaton with AV

Some were. Not that many but a handful.

I lean Vacor as well. Vacor Sunset.

I think the one with yellow is Alley and the rest are Ravenswoods.

I agree^

I guess I lean Champion. Tough call.

Kinda looking like early JABOs.

What size are they? Ravenswood is possible, or Champion.

Likely Champion.

Be glad to take you there Ron!

That's a little far for me. If it looked like for sure good marbles I would be interested but it looks like 2 or 3 of those are most all 7/8"-ish marbles, which would mean probably jugs of JABOs. The others don't look very promising either but it's hard to get much detail. If they are already convinced they are worth thousands of dollars, I think it would be a waste of 10 hours of driving. If it was nearby I'd check it out to be sure. Thanks for the link!

I'm in Georgia. What part of GA are they in?

That's an interesting one for sure! I can see it being Heaton. Not sure about the AV though, Heaton did use AV but not what I'd call "chunks" of it.

Thanks y'all. They are cool looking. I think all were dug, seen by Akro as mistakes I guess.

No, that looks foreign. Here is a leopard skin:

When zooming in, I can't get the detail needed to be sure. Maybe single shots up close would help. From this, I would think Alley, maybe vacor? And late Ravenswood or champion.

Keep it with the Masters.

Alley for both. The first is from St. Mary's factory. Any swirl can exhibit the buttcrack fold but it's the rest of the marble that matters. The buttcrack fold is cause by the ingot folding upon itself. The ingot is a cut section of the stream of glass. Imagine the stream coming from the tank, and the cutter is cutting it into lengths about the size of a tootsie roll. Then fold that tootsie roll in half. Now you have the typical JABO classic pattern. Roll it into a sphere and you can see why you have the buttcrack. But look a the marble you have... that swirl pattern can't occur just by folding a tootsie roll in half, right? That shows more involvement, so it's not likely a JABO classic. Then the glass comes in and confirms. The second marble is also an Alley, but this one is from the Pennsboro factory and a named type, called a Tater Bug. They are pretty collectible.
