Antique Round Table with Matching 4 Chairs

It was manufactured by the Jefferson Wood Working Co. out of Louisville Ky. And from what I could find on the internet they were in business from 1910-1924. It's solid wood everywhere. It did have a leaf with it but it's long gone... It measures 4' in diameter, 2'6" table top to feet. Chairs are 3' feet to tip top, 20" square seat and 1'6" seat to feet. It belonged to my grandmother and granddaddy then passed on to my mother and then to me. It's in excellent condition with zero 'drink marks' anywhere. The close up photograph is the only markings/signature I could find for identification. Thank you again for any and all input.

Good
