1915 Stanley Model 820 Mountain Wagon

Whoever called this car a steamer wasn't a friend of the Stanley brothers, as they hated that designation. It was a Stanley steam car. The brothers were identical twins who went by their initials, F.E. and F.O., looking not unlike the Smith Brothers pictured on a box of cough drops. They set about building what was, without a doubt, the most famous automobile that used steam power to propel itself down the road. The brothers retired from the company while in their 60s, about ten years before the company's demise.

Fitted to a commercial chassis, this was the largest Stanley vehicle ever built and the only surviving example of the 15-passenger mountain wagon. It is believed to have been owned by the Litchfield Shuttle Co. of Southbridge, Massachusetts. It was later used to haul logs out of the New Hampshire woods prior to being purchased by the steam museum's founder, Clarence Marshall, in 1946.
