I could find no markings, the bottom of the drawers have wood slots that the drawer slides in and out on. the inside of the drawers are just plain wood but got some kind of slanted lines in the wood, kinda like a detail pattern. Hard to desribe, there are no staples or nails that I can see, the drawers are all wood and glued together. I do not know what dovetail is, they ae not pegged either.
