London Ordnance Works
1867 Mr. Josiah Vavasseur acquired premises in Bear Lane, Southwark and created the London Ordnance Works, open for business by November 27, 1867. Vavasseur continued the manufacture of cannon, assembling, rifling and finishing steel components roughly prepared by Firth's. He also developed carriages to manage larger cannon, in which he became something of a specialist.
