You were after a 7L in the same case, Art had just put this ancient agate out...and I knew, just knew...! In Danny and Suzi's room, 2015...Since, David Ebbinghouse arranged for Michael Winsten to do the gold mount. Never again will such a bead come my way, I'm grateful, surely! Merry Christmas, Danny, Suzi and all bead freaks!
The Wiki link tells about it's era, clarified for me by Yankee.
