1951 Heil Colecto-Pak Owned By Allied Waste Services This truck had been in service for Mason City, Iowa (most recently in the Parks Department) for a half-century before being retired. It is shown here at Mid-Iowa Solid Waste Equipment Co. in 2006, before it was sold. New owner Allied Waste Services has restored the body, and had it mounted on a 1951 Mack LF.
