Nice find. Congrats...

Since you are the person who found them, what name will you give the mold?

As you probably did... I searched Herz' early work as well as Dale's and found nothing in those small photos; even remotely close... except maybe a flat chain mold, but still nowhere close... and the only reason I mention flat chain is because you might want to include the term "link/linked" in the name.

From what I can see, I seriously doubt it's a recent creation.

Again; super nice find.
