I have a dining table and 6 chairs in very good condition from my Grandmother that I would like appraised. The stamp on the underside is 260-338-3 Touranine by Drexel 279. The dimensions are 65.5" x 43.5" x 29". It also includes 2 leaves that are 20" wide, for a max table length of 105.5". It also includes custom fit table pad for protection, and for the leaves as well. The seats are black leather and the wood type I believe is walnut. Please give me a rough estimation of it's value.
