Yes, Gregg, it has a three-ring stem. The foot seems to be wider in mine but I imagine the size - and shape - of foot is very variable. The stem on mine leans a bit, too!
The possible 1930s date was based on discussion with other collectors and the fact the the glass has a yellow tint which is common for 1930s Chinese work. But I would happily accept that these pedestal weights could be much more modern. Or perhaps they have been made for many, many years.
