Darley
From HighwayWiki
Founded in 1908 and still operating today (W.S.Darley Official Website http://www.wsdarley.com/). Originally, Darley (located in Chicago, IL) supplied practically anything and everything a municipality could require. From fire-fighting and police equipment to manhole covers and traffic lights. They provided a consolidated source of economy-priced materials. Eventually, as competition in this field and state and federal requirements increased, Darley abandoned the various merchandise lines and now solely focus on fire fighting and rescue equipment.
