This domed glass Guardian Service by Century Metalcraft lid is usually called the 9 inch lid due to the outside rim measurement, but the inside lip diameter is 8 inches - it will fit the 8" dome cooker or any round pot or pan that is 8" diameter. It has the number 9 on one side under the knight's head, and DC41 on the other side. The lid has half inch long narrow chip underneath the outer edge, smooth to the touch. Otherwise it's in very clean, good condition.
