Update:
Founded in the 1830's by John Bedford and after 20 years passed to Messrs. Burys & Co. (Limited Company August 1865). Making blister, shear, crucible & spring steel in large quantities for general trade as well as their own use. They manufactured files, saws, edge & engineers tools of all kinds, hammers, miners picks, steel plough plates, knives for reapers, choppers & other agricultural equipment. For more information see: Illustrated Guide to Sheffield, Pawson & Brailsford 1879 Ref: 914. 274 S
It would appear Bury went into partnership with an existing company, John Bedford & Sons (Regent Works was already founded pre 1780) - but the company passed soley to Bury in the 1850's - they appear to have retained the old Bedford mark for their tools...
In the 1880s John Bedford & Sons was at Lion Works, using a different trademark - must stop now as my wife is complaining I am wasting too much time researching this intriguing company history... Interesting they named the new site Lion Works (the old JOBS logo shows a lion), but had to use a new unrelated tradmark...
