Master sort of makes sense with slight chance of foreign

Agree

Left does look like Vitro Easter Egg and right maybe Champion transparent swirl.

Good observations.

Don't look old to me either.

Also, from what I have read, Akro made more slags than the rest of the companies combined so.....odds are Akro unless there are other defining traits.

Here is on of Ron's pics from 2011.

That is cool. I had not seen it before.

They look a lot better than their human counterparts at 100.

Agree

Yes, Stardust and for info, it was previously called Stelaris when Qualatex first had the Vacor packaging and distribution in the US.

Just a bleeding of the color red btween the two ribbons.

Akro cork - sometimes they have that little hook at the end (or start) that sorta looks like a turkey head.

Agree

Slag type with not a lot of white. THe '9' is not like the CAC or MFC type 9's so not sure on manufacturer.

The damage on the two ends is interesting - gives you the impression of some type of pontil or shear marks.

Nice

If you can post some pictures of 4 or so marbles at a time with different views of the marbles in separate pics, we can try and help you.

And last one

And another

Some of mine that I put together many moons ago...

I have not been to the Orange County Show for a couple years, at least. As mentioned above, there were more contemporary dealers at the show itself but there are vintage marble collectors that come to the show and the in-room trading the couple days before the show. The Vegas Show has higher percentage of vintage collectors and the in-room trading is best for that show also.

Could even be a really cool, odd cat's-eye.

CAC here too.

Agreed
