MELON (AKA) dith by Dithridge & Company (1862-1901 merged Pittsburgh Lamp, Brass & Glass Co. 1902), Unknown Date of Introduction
NOTE: Lanae Kilcoyle 2020: Lechner 2 p.92 shows a Flat based shaker as Gillinder. Sid Lethbridge: An 1901 advertisement from China, Glass & Lamps shows this with other Dithridge patterns.Based on the illustrated ad, I would go with documented Dithridge for the flat based shaker. You can see the foot in the cut.
