I have one of those (or close to it) on my desk right now. Look into Fostoria pattern called 'Colony' (somewhere I saw Heavy Swirl). But now I notice the top on yours is just slightly different. Someone else made a very similar candle stick... let me think... hmm.. maybe it will come to me, was another US pressed glass company.
I *think* the pattern is *based on* an old Baccarat crystal candlestick. (The Baccarat ones are etch or mold relief marked on the bottom and have a different treatment of the joints between the sections.
I can't really tell from your picture what the foot looks like. Are there 3 little bumps (hobbs) on the base?
