The Polished Brass Desk Compass with Removable Lid is a beautiful solid brass reproduction of an antique air-damped compass. Under the glass cover is a beautiful, detailed copper compass rose that is marked "Stanley London." The high quality jeweled compass needle settles to North very quickly for timely and accurate readings. The brass compass is 2 3/16 inches in diameter, 1/2 inch tall, and weighs just over 3 ounces.
