A lot of cars used "fork mounted" headlamps in the acetylene gas headlamp era, and even electric headlamps well into the 1920s. They remained popular on expensive cars even after cheaper cars went to simple post or cross-bar mounted headlamps.

One of the last of the "cheap" cars to use fork mounted headlamps was Chevrolet in the late 1910s and first couple years of the 1920s. They had an angled fender skirt mount and a place to bolt a stabilizing rod between the two headlamps. Very much like these. 

There were other similar ones, but my first guess would be Chevrolet.

The distance of the forks may help but they do look like early Chevy.
