Need help identifying model year of early Hudsons

[Centurion]

This photo depicts the first location of the Hudson and Buick dealership in my hometown in Oregon. My grandfather purchased his first new car here -- a 1916 Buick touring. Subsequently, he purchased a new 1922 Essex here.

I need to establish an approximate date of this photo, based on the Buicks and Hudsons parked out front. I assume that both marques are represented. The photo will be utilized in a magazine article, and historical accuracy is important.

Can anyone identify which are Buicks, which are Hudsons, and which model year these cars represent?

Thank you in advance! Be sure to click the bar to see the photo in its largest version.

Here's a second, smaller image -- presumably shot at about the same time.

I'd hazard a guess that it's during the 1914-15 period, based upon the following 1914 ad. The front fenders are so high that the car seems low-slung.
