Your dining table is from what is called the golden oak period which was from about 1880 to about the 20`s or so !! Much was revamped in the early 30`s but styles were changing and these are what we usually see !! The paw type feet are leftovers from the late empire period style !! I would not refinish the table as it reduces the value considerably !! Looks like the legs need to be tightened up as this was a major problem with these tables because the top is pretty heavy and the glue will sometimes degrade and legs splay out as yours appears to have done !! You have a nice piece of american oak furniture and with the leaves,,if all is in good condition,,sell for anywhere between $250. and $750. in my area,, Texas !! Yours would be mid to upper range of that price !!
