Armstrongs of Elswick [PDF ebook] 
Growth In Engineering And Armaments To The Merger With Vickers

Armstrong, the engineers, armament makers and naval shipbuilders was set up in 1847 by William Armstrong at Elswick, Newcastle-Upon-Tyne. This book analyzes Armstrong’s 80 years rise, decline and reorganization, treating it, in some ways, as a case study of British industrial malaise.
