This mould, used to make your rose bowl in Lime Sherbet during the 1970s, dates back to about 1910-11, when it was used to make what we called a "nut bowl" in the iridescent ware that is dubbed Carnival glass today. Originally, this piece was simply designated No. 1401, and the pattern is called "Orange Tree" by most collectors and "Fenton's Flowers" by others. See pages 34, 58 and 118 of the book Fenton Glass: The First Twenty-five Years.
