[1] In 1838 G. E. Jackson, a Birmingham ironmaster, sank "Old Sling" ore mine below old workings at Clearwell Meend.

[2] A factory for repairing boilers, F. E. Watkins Limited, was founded at Sling in 1942, and was still operating in the late 1960s when it also made machine tools and employed around 150 people.

[2] The factory used to announce shift starts and ends using a World War 2 air raid siren until the late 1970s.

Two of the cottages, in the fork of a road to Parkend, were later occupied by a beerhouse called the Miners' Arms.

[3] Several more cottages were built before the 1920s when the growth of Sling began around the crossroads formed by routes from St Briavels to Parkend and from Bream to Coleford.
