Vandyke Oak dining set with four chairs

The table set is solid oak. There are two leaves that insert with metal gears and pegs.The table legs are carved and connected by a cross bow. The chairs are carved on the back face.There is a marking on the chair that reads Vandyke. My sister picked up the set in 1974 near Cleveland,O.and gave them to me. I don't know the age but guess it to be circa 1940. I stripped it some years ago and added some varnish.
