Winfield (R. W.) & Co.
R. W. Winfield & Co was founded in the 1820s by Robert Walter Winfield at Cambridge Street Works, Birmingham and was one of the largest and most celebrated of the Birmingham brass founders. The company was well known for its brass bedsteads, but also made armchairs with brass and iron frames, curtain and cornice poles, and other household fittings. They purchased Camm Brothers in 1882. Thomas William Camm left the business in 1888 to work independently as T W Camm.
