The green base swirl is an early Vacor Wicked Owl.

Personally I don't see how spin direction in a fully machined SWIRL marble is important or plays any part in company identification. Akro used the spinner cup to obtain the CORKSCREW pattern which controlled the end result. SWIRLS (not corkscrews) are completely directionally random. Overall pattern, glass quality and color(s) are what makes an ID.

I do a little wood sculpting from time to time and love to see the different types of wood grain patterns. I also love visual puzzles...so I'll guess! Table-Oak, Top left- Maple, Bottom left- Rubber, Right-Walnut . I also really like your shorebird sculpture and it gives me a good idea for my next project!

Yes to Ravenswood - beautiful old glass and I would call it an early premium type.

Classic Ravenswood.

Not a Christensen. RAVENSWOOD.

VaMarbles - stunning pair! I'd sure have a hard time letting go of BOTH. Sell one -keep one. That would be my agenda. I am the type of collector that doesn't need mountains of dupes, just one fine as possible example of each type from every maker. Sort of a mini marble museum! I have a long and seemingly infinite way to go - which makes me happy and hungry for the hunt.

There is no oxblood here and this marble is not buffed/polished IMHO. Also, the seller is a highly respected member of the marble community who has written academic tutorials on how to detect buffed/polished marbles, as well as the scientific properties of oxblood glass. If it was buffed/polished he would recognize and acknowledge it I'm sure. He is meticulous with his inspection and descriptions of his marbles up for sale. This is a rare color combo for a Popeye ( how many of you have one?) - but I am surprised at the final hammer myself.

No - that's Vitro Whitie. The green pearlized patch glass is completely opaque and has the luminous sheen and luster of a pearl as seen in this closeup.

Not thinking Oxblood here, but am thinking CAC American Agate.

Sorry....deleted my double post here. Might as well post a photo of my Akro Blood &Bones.

Looks like what is known as an Akro Blood & Bones. The base on mine glows UV but maybe they all don't?

Eine Menge Geld...on a string!

The above Akro box is a real rare beauty alright, but those look like Akro TEAL slags and not AQUA. Of course there's a chance the color of the photo is off. In my experience true Akro teals are much harder to find than aqua. The Akro teals will also UV react. Check your slags and see how many Akro UV Teals you find!

Appears to be a Peltier Acme Realer. That particular green color, patch shape and base glass quality are correct for Acme Realer. One of the largest I've ever seen!
