Seems I may have been way off the mark from the beginning.
After thumbing through the book " THE COMPLETE CUT & ENGRAVED GLASS OF CORNING" by Estelle Sinclair Farrar and Jane Shadel Spillman, the pitcher relates favorably to a late version of T.G. Hawkes
GRAVIC line. Some relevant excerpts from the book: " the Gravic designs are usually fruits and flowers, which were copper-wheel engraved in the beginning and were later stone-engraved, as that was a less expensive process. The engraved flowers usually had mitre- cut leaves and stems". Concerning their wares from the 1920s another relevant quote from the book: "Engraved wares of the same period are usually simple and make much use of stone-wheel work and gang cutting. The designs introduced in this period stayed in the Hawkes line until the end. With few exceptions they are lighter in weight and are simpler compared with pre-World War I patterns".
