The prototype Douglas World Cruiser, Army Air Service serial number AS 23-1210, McCook Field prototype number P-318. She'd later be named "Boston II." The aircraft was designed and built to US Army Air Service (USAAS) specifications for the purpose of completing the first flight around the world (hence, the ability to operate either with interchangeable fixed handing gear or floats) . Four production aircraft were built for the flight. They were named, "Seattle" (AS 23-1229), "Chicago" (AS 23-1230), "Boston" (AS 23-1231), and "New Orleans" (AS 23-1232). Both "Seattle" and "Boston" would fail to complete the journey. "Seattle" would crash in Alaska on April 30, 1924 (the story of the survival of her crew is worth learning about). "Boston" would be forced to land at sea near the Faroe Islands after her engine failed. She'd be irreparably damaged in the forced landing, and would sink while being towed by the light cruiser USS Richmond (CL-9), on August 3, 1924. After the loss of "Boston," the prototype (AS 23-1210) was pressed into service for the remainder of the flight, now named "Boston II." It would join the flight at Pictou Harbor, Nova Scotia, on September 3, 1924. Read more: en.wikipedia.org/wiki/Douglas_World_Cruiser en.wikipedia.org/wiki/First_aerial_circumnavigation

This would appear to be a Liberty L-12 aircraft engine. Over 20,000 of these V-12 engines would be manufactured between 1917-1919 by various manufacturers as part of the war effort. So many were built that its use would be specified for a number of aircraft through the 1920s. See: en.wikipedia.org/wiki/Liberty_L-12
