It's from that era where there were lots of different start up manufacturers of automobiles in existence. These companies would come and go so it takes a person that is familiar with a lot of those cars to be able to recognize these types of parts. There are not as many people out there with quick knowledge of the possibilities as there used to be. I worked for a guy that had that type of knowledge since he worked for Bill Harrah back in the day but sadly, he passed back in the 20-teens. A person has to do a lot of research to gain that type of knowledge in the modern era.
