"The North Brothers Manufacturing Company (North Bros. Mfg. Co. or more simply North Bros.), was an American manufacturer based in Philadelphia, Pennsylvania that specialized in the making of hand tools, small appliances and some specialized power tools. They were family owned and operated for over 60 years before being acquired by the Stanley Works in 1946. They are probably most well known for their line of tools, particularly the "Yankee" brand of ratcheting screwdrivers." - (Wikipedia (en) 23.09.2021)
