According to The Glass Candlestick Book, Vol 2 by Felt and Stoer, this candleholder was made with three different variants in 1943 and 1944: Variant # 1, which has a crimped foot; Variant #2, which is shown with its saucer foot; and a cupped foot variety that was not numbered. The saucer footed variety is hardest to find because only 773 of them were made.
