This is a Vintage 1945 75mm Trench Art Vase. The shell casing dates to 1945 as it is stamped on the base (I believe it is by BB Co.) The Vase is inscribed "Bernard M. Powell Phu Bai, RVN 1965-1966" 10 1/2 inches in height, 3 3/8 inches in diameter at base, 4 inches in diameter at its widest point. Good Condition, a couple minor dents, tarnish.
