I'm going with Pelt Rainbo on the top left. Not NLR. The one to the right of it might be Jabo. The green one might be Asian. The reflection is softening the detail I'm looking for, so I won't rule out Master, but I'm seriously considering Asian. Not seeing enough detail on the bottom left.

I'll vote Vitro on the larger ones.

My thoughts, left to right Akro, Pelt, Pelt, Alley, Master

Eek. I'm not seeing Marble King Rainbow. My brain is a bit mushy tonight. My first thought was Vitro, but I am not placing the style if it's Vitro. Maybe it's Akro.

I think this one could turn out to be a Christensen Agate. But do NOT take my word for this! Wait for more opinions.

Oh gosh, with those colors, and now that you mention it, "of course".

Having two ribbons of one color and a third ribbon with a second color is unexpected. For age, I would have guessed at least a little later than "early 60s", but I don't know.

Yes, only Akro for corkscrews. I'm seeing all of those as being essentially two-color marbles. Yes, Prize Names.

IMO, some unrecognized company in Asia.

Not seeing the pix.

You have some old some new. The way they're arranged makes it hard to point out which is which. The ones with three narrow ribbons, in three colors equally spaced around the marble, those are modern Asian. The green on white at about 3 o'clock -- Akro Moss Agate. The white with a large red patch and smaller green patch near the center -- Akro Tri-Color Agate.

First pic: Peltier Multicolor Rainbos. From the NLR period. I agree with NLR Rebel.

My only guess: Vacor Picasso https://www.billes-en-tete.com/detail.php?id=45

Akro on left. I'm confident of that. I don't know on right. With the colors my first thought was Vitro, but with the structure you're right to consider Akro.

Maybe Jabo on the top left. Maybe Akro on the bottom left. The green ones on the bottom might turn out to be Akro also. Or Vitro? I'm not placing that lime shade. Maybe Akro on the top right also. I thought I ought to recognize the top middle ... but then I saw the small additional piece of yellow in the last photo and that was out of place on what I thought it might be. To ID patches, I often need to see seams. You show a seam in the bottom left marble of the first photo. A little off-center, and centered is better, but that's the feature I look for.

Wow ... was it 8 days ago that you made that last post? Time has flown.

Thanks, Terry.

Hoping @Alan can help.

There are some JC's in this list: https://marbleconnection.com/topic/20926-contemporary-marble-artists

Second from the right looks like a slag. The rest look like they're from WV swirl companies.

My first thought on bottom right was modern Asian ... but not seeing enough structure to be sure. Long seams on top left made me think of Vitro or MK. Solid color marbles usually go unidentified.

Not seeing any clear patterns ... so I'm going with WV swirls for all.

All MK Rainbows. The ones with 3 colors are called Tri-Color Rainbows. Not sure what to say about "similar styles". Similar is relative ... but these are MK. If the green rainbows have much aventurine I've heard people call them Grasshoppers.

interesting .....
