Jacobean revival......probably 1920's....perhaps earlier. Looks like it could be from England as I have seen a lot of "cartons" of European antiques with things like that....barley twist turnings on the chairs....which likely were not originally a set with the table.
Very Very nice....

That style started in the 1830s, in Architecture as "Gothic revival" and had its last gasp in the 1920s in Sears Catalogs under the name of "Baronial". It went with the Tudor cottages and desire to emulate the rich who were bringing back entire castles or the innards of them.

That is more elaborately carved than most of the Jacobean revival stuff I have seen. the cheap versions went in for turned, but not carved, legs and scroll-cut ornamentations.

I like the way the seats of the chairs echo the wall, too. it's subtle but elegant. They almost look like Spanish Colonial revival.

It's hard to tell from the pix, but if the leaves are tucked away under the table and then pull out to be extended , the table is know as a Refrectory Table .

A refrectory table is a table that was used in a "refrectory"...a dining hall, as in a monastary. The term has nothing to do with the leaves but refers to a very long narrow table.

Linda , you know what I think about your opinion .

Not opinion....fact.

It's spelled "refectory" FWIW.
For it's genre, it's probably as high-quality a set as you're ever likely to see.
I really like the way they incorporated an ionic capital volute into the leg design.

Linda let me rephrase my previous statement .
It's fact that you know what I think of your opinion.

Casey - ya know when I looked back I realized I had typed Refrectory and not Refectory .

I am chagrined that I followed "Stocky's" spelling without checking.
But the issue is not how it's spelled... that is important... but that a refectory table is not defined by the kind of leaf it has but by the shape and size of the table and configuration of the legs.
