I have two questions I guess mostly directed at Sunoco collectors or oil bottle collectors. Which Sunoco oil bottle is older the plain bottle or the one with the wavy lines at the bottom which are embossed in the glass? If they are the same time frame, is it because they were made by different glass companies or is one an upgraded variety (like this kind came only with the chrome spouts)? Same question with the porcelain bottle rack holder as there are two styles; the one with the plain square signs as seen by the legs (usually this kind does not have any porcelain sides) and the second kind with the curved porcelain around the bottom legs and has all four porcelain sides? I believe that the square sided one is older but I am not sure. Thanks for any information you can provide. John
