NOTE: Terry Wells - Opalescent Glass from A-Z rev. ed (2000) p. 68, William Heacock, originally attributed this pattern to the West VA Company Hobbs, Brockunier. However, the editor, JoAnn Elmore, who revised Heacock's works, notes that the pattern may have been made by another company, possibly Phoenix, Northwood, Dugan or even a British glass works.
