This former Buffalo Airways DC-4 (hence the green fin) was always equipped with tanks and booms, initially for agricultural work with Conifair Aviation and later with Buffalo Airways. In 2011 they based the aircraft at Punta Gorda (FL) and placed it on the US register as N55CW to allow it to operate under contract with the US Coast Guard for oil spill dispersal work (using the same spray gear), mainly in the Gulf of Mexico. In Apr 2013 it returned to Red Deer (AB) for the removal of all spray gear, then returned to Florida in 2014, where it was stored at Keystone Heights. It remained there until 27 Apr 2022. On that day it was flown to St. George (UT) on delivery to the Western Sky Aviation Warbird Museum for static display, as seen here.

Buffalo Airways DC-4 N55CW departed Keystone Heights Airport in Florida on April 27, 2022 for the Western Sky Aviation Warbird Museum in St. George, Utah, where it is on static display. Departing shortly after 12:00 noon, the aircraft arrived five hours later in Fredericksburg, Texas for an overnight stop. In what will probably be the aircraft's final flight, it departed Fredericksburg late the next afternoon and arrived at St. George Regional Airport four hours later. The veteran flight crew consisted of pilot Bob Steenbock, co-pilot Mike Stallman and flight mechanic Frank Moss.
