There is a 1911 Stanley model 72 up for auction September 15, 2012 in Spearfish South Dakota. A model 72 Stanley is a 20 hp Roadster. Find the listing at [www.vanderbrinkauctions.com]
No photo shown, but the model 72 was listed after the 1900 Mobil type 3 steamer. The 72 was listed as a "Stanley Brothers, #72, Beautifully restored, 2-Piston Steam, Red w/Black Top, Amazing!." If the Stanley Brothers #72 is referring to the Mobil, then what does # 72 refer to with the Mobil? 72 inch wheel base? Originally, the model 72 was a 1911 Stanley mid year release of a aluminum skinned bodied roadster. Nowadays, I see the model 72 referring to 1909 to 1911 20 hp roadster receations with only a wood body. There were so many great cars listed for the auction without photos, I didn't expect to see a photo of the Stanley.
