Dear Lolo,
Your candlestick was made sometime between 1933 and today. The numbers are pattern or design numbers, they are not related to Gorham's dating code marks.
Most American manufactured sterling will have numbers, or a mix of numbers and letters stamped on it. This type of spun and weighted sterling ware was on the low end of Gorham's production and they did not tend to date mark it.
Pretty pattern, it probably corresponds to one of Gorham's popular flatware patterns and was meant to grace the dining table with it.
Cheers,
AinA
