BEADED FLANGE (AKA)
Co-operative Flint Glass Company (1879-1930s), Introduced: Unknown Date
• NOTE: Sid Lethrbridge: There is an article in All About Glass Vol. X No. 1 titled “Finial Answer?” that lays out the evidence that allows us to assign Beaded Flange to Co-operative Flint based on the use of a finial specific to that firm.
