The Whitney pattern is shown in a 1933 trade ad on p 71 of Hazel Marie Weatherman's "Colored Glass of the Depression Era, Book 2." This reference states that the pattern was named after Harry B. Whitney, a glass salesman.
On page 101 of "The Encyclopedia of Duncan Glass" by Gail Krause, under Bowls on Second Row is the exact same bowl noted as " # 75, 11 in. crimped bowl."
As shown in a 1943 catalog in the Weatherman book, Duncan & Miller also designated their Diamond pattern as # 75.
