Vincent toolkits used a lot of  'Jenbro' spanners made by the Jenks brothers. It is unclear as to when Jenks Brothers Ltd. was formed, but they had branches in Leeds and Newcastle Upon Tyne, in addition to head office premises in Cleveland Road, Wolverhampton. They were engaged in producing motor accessories, small tools and machines under their trademark name 'Jenbro' (presumably a combination of 'Jenks' and 'Brothers'). Some time before 1937, the British Tool and Engineering Co. Ltd (Britool) became a subsidiary company of Jenks Brothers, with Jenks Brothers becoming distributors for them. In 1937, Jenks Brothers Ltd. and the British Tool and Engineering Co. Ltd., (Britool), were taken over by John Shaw & Sons (Wolverhampton) Ltd. Also in 1937, John Shaw & Sons took over the old Clyno factory in Bushbury and moved its two newly acquired subsidiary companies, Jenks Brothers and Britool, to the new premises. In 1969 Britool were taken over by James Neill, of Sheffield, making them a member of the James Neill group of companies. In 1991 Britool was bought by the international group Facom and, around 1980, moved from Bushbury to Walsall Road, Cannock, where they continue to manufacture tools.
