Engineering Tool Works are first depicted in the south western corner of this site on the 1981 OS. Through the twentieth century the works appear to have been successively rebuilt and enlarged eventually expanding to the north across the former residential terraced streets of Anlaby Street, Brough Street and Cottam Street. Presently (2005) owned by Kennametal Hertel Ltd who are manufacturers of machine tools. Legibility of early works likely to be no more than fragmentary.
