This enterprise was one of the pioneers in the Britannia metal trade.   The founder was Richard Constantine (1763-1836), who was born at Giggleswick, Yorkshire.  He became a Britannia metal manufacturer in Sheffield, where he was partnered by Stephen Bromley.  This ended in 1791.  His next recorded partnership was with Samuel Ellis and William Littlewood.  The latter withdrew in 1794.  Three years later, the Sheffield directory listed Richard Constantine as a maker of white metal goods at Pea Croft.  Henceforth, Scotland Street was the factory’s location during the early nineteenth century.  James Dixon is known to have been trained at the company.   Its last listing was in 1828.  A notice for the auction of Constantine’s tools and stock appeared in The Sheffield Independent, 15 January 1831.  He was buried on 4 April 1836, aged 72, in Ecclesall churchyard.  His death does not appear to have been reported in the local press.
