The vast majority of drum tables I've seen are colonial revival ca. 1930-1950, from companies like Duncan Phyfe. Although this table resembles those superficially, I think it is decades earlier.
I'll reiterate: Very early 20th century or even late 19th. It looks like Empire revival, late Victorian or post-Victorian, particularly the bundled colonettes. I'll stick with the small center table function, since the drum does not rotate; therefore, there needs to be open space on all sides to access all the drawers. It also works as a plant stand whether the top rotates or not. I'm inclined to think that it doesn't, based on what Ameru said.
