I just had a friend drop off an old All American 15 1/2 quart Pressure cooker that his family hasn't used in years. He said that it has been stored away and he was glad to give it to me for making sauces. All he wanted in return is a nice sampling of my creations, as he is a fellow chili-head. What a deal! I have been on All American's web site before and am planning on replacing the gage and relief valve as these are easily replaced. Looking at the stamped number, 7, I believe that this is an old one, but still looks to be in excellent shape.
