I'm seeing aventurine and JABOs. I'm betting they are around 3/4" too. Out of round also goes along with that. Definitely not Leightons.

Nice ones Ric! A nice Cosmic Rainbow shooter

Akro prizename or weak special on the first, a nice Alley on the second.

X 2 on Alley.

Tough one. I don't think it's a Heaton. What size is it? Pattern is Ravenswood-esque but not enough to commit.

I agree, Imperial.

Got to find some alligator eyes one of these days Nice

Yep, Akro.

Alley then in my opinion.

I agree, chance of either. Size would help. If it's 21/32" or bigger I'd put it with Alleys. If it's 5/8" or smaller I'd go Ravenswood.

I'm seeing a WV swirl or possible CAC transparent swirl.

A yellow Master brushed patch. Those (yellow) have been very hard to find in my experience.

I agree with goldstone. They often have bands in them of glass that didn't mix in or do whatever was intended. I think these can be both old and newer.

Definitely Vacor.

On some marbles like the JABO jorkscrews, just hitting the smooth rollers could put a cork pattern on them, so I think it's entirely conceivable that hitting the spinner cup would definitely swirl the glass. It has a much rougher surface and grooves to make it catch the glass and twist it.

Some nice AV marbles shown. Here are a few more. Some Pelts Some Alleys Some Akros

Crazy metallic bruiser! Peltier Toucan. Less than 10 of these known so far. A few years ago it was only 3. Lava flow metallic PPP

There was no rod apparently. What looks like a rod in the one drawing is shown to be one of the grooves cut in the spinner cup in the unaltered drawing.

These are some spinner cups. You can see there were different designs in the cups, just cut outs to give the cup traction, grip to spin the glass. You can see on the base where a set screw made marks in it to hold it in the fixture it's mounted in on the photos Alan shared. Some have holes in the bottom, some don't. I would presume to vent air in order to keep bubbles out and to let the glass fully seat into the cup.

Agreed, Master brushed patches. If pics might help you with them, here are some of a lot I got not long ago, mostly brushed patches.

CAC all the way for me. You can get a nice alley or two for it I'm sure. Just not from me , I like the alleys too.

Thanks. It's not really rough to feel. I've seen 3, 2 are in my collection. I'm sure there are more. A photogenic Easter egg with bright robin egg blue

CAC crossed my mind too. Not sure.
