Confusing drop leaf table. Are these legs original?

Thanks for posting the other pic. The legs on the first one look a bit fancy for the style and may be from a walnut table with the top replaced. This opinion was based on looking at other detail pics. I went ahead and used it to show the casters The second one looks all original and is more similar to the OPs.

More formal dining tables from this same time period can have some really large legs. Talk about clunky!
