My apology for the delay I have been traveling on business since all last week.
Your set is done in a mix of early English styles such as Jacobean, Tudor and Medieval, though your set was made circa 1900 and made during the Arts & Crafts period when these early styles were being revived and were in style in homes as the furniture decor to have. From the images this appears to be made of oak and the top is quarter-sawn. The form of the legs are referred to as 'cup and cover' and the grape motif is symbolic of bounty, harvest and mirth.
On today's market, the table realistically sells for $600 - $1000 and the chairs $125 - $200 each. The suggested insurance or replacement value is $3000.
Just checking in to see if you viewed your answer and if you are seeking further assistance?
Please let me know.
