My great-grandfather owned one of the first automobiles in La Grange, Illinois. He is shown in this photo along with his wife and my grandparents. I'm trying to figure out what kind of car it is. I'm guessing that it is a Peerless of 1903-05 vintage. Am I right? Some Duquesne and Yale autos also look similar. I have read that auto makers of the day often had some other company build the body (to the customer's specifications, I guess). Exactly what parts are considered to be "the body" (e.g., does that include headlights, fenders, engine compartment)? So, in trying to identify the maker, which parts are most important to look at, and which ones may have been an option provided by the body maker? Bottom line: Does anyone know what is in this old photo?
