Some hockey historical websites list a team called the Richfield Oilers that played in the California Hockey League for the 1927-28 season as being based out of Richfield but it is more likely the team was based out of Los Angeles and played out of the Palais de Glace (Los Angeles) as the former Richfield Oil Corporation, now known as ARCO was based out of Los Angeles.
