This firm was launched in the 1920s at Granville Works, Granville Street, by Charles Edwin Jenkins (1876-1943) and Arthur Ringrose (1891-1957).  Jenkins was from Heeley and first worked in a cutlery warehouse. Ringrose (born in Somerset) was a clerk, who withdrew in 1934. 

Jenkins died in 1943 and was buried in Norton, but Jenkins & Ringrose continued at Granville Street.  In 1952, an advertisement in International Cutler offered a range of cutlery:  carving sets, table and dessert knives, canteens, bread knives, butchers’ and cooks’ knives, and painters’ scrapers.  It had apparently ceased trading by the end of the 1950s.  No trade mark has been traced.
