Been hauling some things around for about 30 yrs. Dusted them for 15 yrs. prior, in my great aunts house. One is this beautifully carved buffet. Can find no marks, and I've looked! Dove tails are not uniform and are located at front and back of all drawers. There is a hidden drawer, top center, with release button located below. Center opens by press-release and holds 3 pull out shelves for, I'm guessing, wine. I would like to know where it came from, how old it is, and what it might be worth?
