The overall shape and the maker's mark (not found in the Tardy index) have a Continental flavor to me about them, but the very light construction perhaps hints at an American origin, so I'll try here first. The drop has four faces, and there is a mid-ridge down the stem underside. The spoon was perhaps made from hand-hammered sheet, as evidenced by a wavy delamination down the middle of the stem underside. As opposed to the very light overall construction, note the very thick finial tip, somewhat unique. There is an amateurishly applied, prick engraved script "D" monograph. Might anyone recognize the maker's pictorial mark or the spoon's regional style? TIA!
