I believe this piece to be an M2611A but not sure as i'm not a porcelain expert. It is embossed on the top umbrella Ohio Brass (O in a B) and on the left side of the OB is a 3 and on the right side of the OB a 5. The embossing is faint but readable. As you can see in the pictures its a two tone color having a dark brown umbrella with a gray mottling over it and the bottom part is an Olive shade with light reddish brown rings going around it. Its also in Mint condition. It measures approx. 9 inches across the top and is 6 1/4 inch tall and weighs approx. 9 pounds. I've added a pic of the base as well. Asking $40.00 Cdn. plus shipping.
