I have a set of these, which I thought were Ford according to the paperwork that happened to be in the box, but was told otherwise. They were part of my uncle's hoard of "stuff". Just now getting around to posting them here and asking for an opinion and help. The only markings are JE and 154. They're about 4.5 diameter; I suspect DeSoto Hemi, but have no way to verify. Thanks in advance.
