1920 Ford/Howe Model T Pumper Wheel.  The Howe Fire apparatus Company adapted its fire pump and booster tank to a Ford Model T chasis for several hundred of these modest lottle pumpers for the U.S. Army in World War 1.  This one went as surplus in 1920 to the volunteers of Germantown, Illinois, where it saw service until 1956.  The long "squirrel tail" style suction hose came in handy for drafting water from rivers or ponds.  The engine could draft water without getting the truck too close to a soggy river bank.

On display at the Hall of Flames Museum in Phoenix, Arizona.
