This is taken from museums-sheffield.org.uk The coffee pot was made by Richard Morton & Co of Sheffield. This firm made a vast range of goods from Old Sheffield Plate and was based at Brinsworth's Orchard (now Orchard Street in the city centre). The coffee pot is stamped four times at the top of the body with the mark 'M.Co'. In 1785, the firm's mark changed to a cockerel. John
