It's not one I readily recognize. JABO seems like a possibility but it has a pretty intense orange peel surface so I am not too sure, and I wonder about other possibilities.
Single color swirls in transparent glass are often difficult to ID. But given what appears to be batch white glass and the structure, I am leaning CAC, although it could be something else. Many of the swirl companies made similar marbles.
It's an oddball and at that size, I'm not really sure what to think - this may be a hard one to get a firm ID on. Although, it looks to me more like a machine made marble that got spun than a hand-gathered MFC, but I can't offer much more than that.
I notice you also have a few transparent-based Whities in your Conqueror group. They have a transparent base with two white polar patches and two same-colored ribbons around the equator. There are also a few Tiger Eyes of various types in the mix.
A general rule of thumb . . . if there is no red on the marble it is not an All Red. Like Steph, I see some Blackies in your All Red group and you have some of the older Black Line All Reds mixed in with the newer type of All Red that lacks the black ribbons between the polar patches.
