NOTE: Sid Lethbridge 2022: This pattern started the Millersburg Glass Co. as No. 400 aka Flute pattern. After their successor Radium Glass went out of business the factory, stock and equipment were acquired by the Jefferson Glass Co. of Follansbee, WV in late 1913. A number of moulds in this pattern were sent to the Jefferson Glass Co., Limited factory in Toronto and became part of the No. 1600 line, a joint venture between Jefferson (Follansbee) and Dominion Glass (Montreal). By 1916, Dominion Glass had complete ownership of the Toronto Jefferson company. This crimp shape is indicative of Millersburg/Radium production
