There are some bigger Akros--dug--that look like this.
They are sold and have been sold as "Large Sparklers"
Yours looks to be 5/8" so I agree with Master.
Marble--On!!
Back to the OP---love it!!
It is not"just a "Dragon" or not just a "Rainbo".
It is a special NLR Dragon imho.
This is a very nice find and not very common.
Marble--On!!
Size always matters. I am thinking that his one is “shooter” sized.
I agree with Ric.
This one is a bit weird but I think Pelt is the right call.
Maybe @cheese or @Chad G. will have a better handle on this one.
Marble--On!!
It could be a Vacor "Streamer". Transparent base glass with a single other color.They are more of a swirl than a cateye.
The Vacor web site appears to show a blue one with some white involved.
Marble--On!!
MMMM Rubens and Popeyes--it does not get much better.
They may both be Popeyes--it depends on the collectors eye here.
The one on the right does appear to have oxblood--kinda like the runny ox in a "silver oxblood"
Nice marbles!
Marble--On!!
