According to Jim Retzloff, the sherbet (33-A) is described as "Vertical Optic, Iridescent Stemware" in a Hocking Catalog. The sherbet is described as "Genuine Cut Glassware" and "Crystal Cutting No. 6" in a Standard Catalog. To make things more complicated, the sherbet came is several sizes, and, with or without the sunburst pattern in the foot. All examples are described as item Number 33.
Page 19 of Hocking "Glassware" Catalog B illustrates the 33 sherbet with a grape cutting No. 6. I would suggest for the purpose of the gallery, the cutting should be described as Standard's "13 Grape" or like Weatherman just "Grape." Weatherman also illustrates the sherbet (G33) with the Number 6 cutting on page 328.
Jim says that he has a note in his records that the "Grape" cutting was also described as Number 95, but he doesn't have a reference for this description.
The "R" or "G" prefix (R-33) indicates color, Rose or Green glass respectively. 33-A would indicate an iridescent coating.
