So Jordan, as it is not round, it is unlikely to contain rolled up tin foil and wax paper. By what means does it achieve its necessary characteristics? (capacitance)
The capacitance (measured in microfarads) is important. Being not enough, or too much, will cause the transfer of material one way or the other at the contacts, markedly shortening the life of the contact set. British Fords around the 1970s used to have the mfds painted or stamped on the condenser body (eg. 7 mfd, 8 mfd) I think I have owned flathead v8 condensers similarly marked.
