Based on a drawing on replacements.com, this goblet is most likely Val St. Lambert's Simplicity pattern. It is similar to Fenton's Lincoln Inn and to Dorflinger's miter-cut pattern called Renaissance. The main difference between the Gallery pattern and Dorflinger's is that the spaces between the horizontal and vertical cuts are rounded on Dorflinger and rectangular on the Gallery piece. These spaces are also rectangular on the Val St. Lambert drawing.
Details of the Dorflinger piece are based on image #32 of four goblets in the 2005 edition of "Identifying American Brilliant Cut Glass" by Bill and Louise Boggess.
