GUARDIAN SERVICE COOKWARE IS AGAIN BEING MANUFACTURED and as a Guardian Service distributor I pride myself in providing many guardian products in order to enhance your cooking abilities. For this reason, I am now offering new replacement glass covers for distribution throughout the UNITED STATES! This auction is for the casserole both top or bottom or small fry pan (glass cover only,) also known as the 51X 9 1/8" inside diameter. These are the exact replacements to the original covers that were used decades ago. However, these covers are not to be placed in the oven, as they are not "oven proof." The cookware was originally designed for top of the stove cooking. This replacement glass cover holds the Guardian Service emblem on each side of the glass (just as the original did). The new replacement glass covers are specifically designed to be used with your original Guardian cookware. Shipping and Insurance $12.25 in the U.S.A
