This Amber two-light candlestick, produced briefly in 1930, has a decagon base and is missing the finial at the top of the arch that is found on later production of #647. Instead, it has two small curlicues.
Version 1 had no decoration at the top of the arch and a decagon base. Version 2 is shown above. Version 3 when introduced in 1931, had the decagon base along with the usual finial. Eventually, the version 3 decagon base was changed to round.
