In Ravenswood, look for a more organized ribbon. A stream you can follow that swirls in a more graceful manner. Not that Heaton can't do the same, but many Heatons have this short stream construction and RWs have a longer stream making up the marble in general.
Nice! Those are St. Marys Alleys. Looks like they are the contents of a box or bag and have stayed together through the years. The one looks like a fancy or exotic type or coral I think. Would be a great group to keep together and not mixed up with others to use as fill for a box or just for posterity.
About half of corks spin one way, half the other. Not sure how the direction one spins can be a trait. Pelts can spin either way too or not at all. How do you explain the ram's heads then, which swirl both ways?
I find these in bags at thrift stores. They are intentionally made like this (sort of a pyramid/gum drop shape), not intended to be a marble. They are for flower vases and decoration. Modern.
Yes on Heaton B/Gs. We used to put them with the Champions because like Ric says, Champ made them too and we didn't know Heaton did until recent years. The champ ones have a whiter base and a busier "wad of chewed gum" pattern generally. Here's a champ single pic and a Heaton collage pic.
