reminder, if you want a car ID'd, please tag with #DavesCarIDService and I'll try to get to it in order submitted
But I will make an exception in this case, and I am pleased to inform you it is a circa 1911 American Underslung, with its proud patriotic soaring eagle radiator ornament. The first factory low rider, and one of my favorite brass era cars.
If you visit Chicago and want to see some interesting obscure architecture, visit "Motor Row," aka 3 blocks of Michigan Ave south of Cermak. The first car dealership row in USA, & the buildings feature names of their cars - Locomobile, Marmon, Pierce-Arrow, etc
underslungs were able to achieve their remarkably low stance (for the time) by locating the axle *above* the frame rails and below the springs. Other versions had springs at the bottom and frame on top.
