This pattern is similar to Hazel Atlas Prime Rib and Fenton's Sheffield patterns.
This bowl is also found in a cobalt blue with a metal base attached as shown in the thumbnail. The blue bowl is 9 inches wide and 4 1/2 inches tall. The metal base extends 4/10 of an inch below the glass base.
It was dubbed "Prime Rib" by Hazel Marie Weatherman on p.393 of Vol.2 of her Colored Glassware of the Depression Era.
