This is probably from their 3027 Finest English Cut Crystal Suite. Sizes were 6 1/2" Hock, 5 1/2" Tall Goblet, 5" Tall Champagne, 4 1/4" Claret, 3 3/4" Sherry, 3 7/8" Cocktail, 3 5/8" Port and 3" Liqueur.
From Catalogue #34, dated 1960.
also in #29 1956/7, #33 1958
Not in #26 1954
So yours would date from 1955 at earliest and continued to be available at least until 1960. There was a similar design range, slightly more complex from the 1930's which yours obviously replaced
