The second one may be a “wirepull”.
If you can follow that strand of glass all around inside of the marble without noticing any breaks, there you have it, one strand only in wirepulls.
Marble—On!!
Cool looking marbles for sure.
The one with the yellow involved is a poorly made cateye imho—still a cool find—no maker from me.
The other one—if it was intended to be a “bead” would have a hole through it more often than not. It is an odd duck and it reminds me of a “bullet mold” marble.
Marble—On!!
I think that the two darker ones are contemporary—made to look like old—the larger one may be a WVS.
No “bullet molds” here at the least--imho.
I appreciate all opinions and wish for some more.
Nice marbles and size matters here.
Marble—On!!
Vacor is a part of "Glasfirma"--they make the marbles.
I do not think that these that you posted are Vacor marbles.
I wish that I had some to compare with yours in this size--not.
They are nice marbles and I would not call them Cateyes.
More opinions are needed and welcomed.
Sometimes a few from the deep South America's or Europe will show up and flabergast us all.
Marble--On!!
I agree, not a cateye.
It may be a Master Made marble but the first image makes me lean a bit towards a foreign made marble( english?).
I am not used to seeing Master Made marbles fold in on the cutoff like this.
Marble--On!!
