Alley agate from the St. Marys factory.

Alley agate from the Pennsboro factory.

Heaton.

X2 RW

X 2 Alley.

Last one is Laura Berretti.

Glass and pattern. Smooth creamy swirl, bubbly syrupy base, CAC pattern, etc...

CAC.

No on the cateye. The clearies could be from anyone.

That one doesn't have strong traits. Just based on size and colors I would lean to later Alley. The pattern doesn't really show it but...

The base glass is only green. Then you have the black and orange/red/yellow. I believe Alley tried to reproduce them at St. Marys, maybe more than once, and came close but they were different. Here is a carnival for reference, from the West Virginia Swirls Identification book.

yep

Alley but later thana carnival. Close though and still very nice!

WVS or not, every company made some that size.

Champion to me. Later one.

Not sure but seems likely to be RW.

Cairo.

Maybe. What size?

Yeah it looks good on my second look too. Call it calligraphy IMO.

Look at the left row of calligraphies in Ron Shepherd's salesman sample box. Where does flame end and calligraphy begin? I would put this marble next to my calligraphies and consider it to be one some days and not one some days depending on how it hit me on that day. It's borderline. Some of the other calligs in this case are less busy than the OP marble, for whatever that's worth.

Sure looks close Rick. Here's some cullet dug at RW by Ron Shepherd. The white isn't as stringy and I don't claim these to be exact matches but we know how marbles vary...

Agreed, Navarre.

Alley is right.

That's 100% Vacor.
