This merchant was established in 1866 in Baltimore and Sheffield by William R. Penniman and C. Wright.  It had a Sheffield warehouse (and packing rooms), with T. C. Hill as local manager, and three marks:  a green label with a drawing of Battle Monument, Baltimore, alongside the words ‘Superior Spring Cutlery, manufactured at Monumental Cutlery Works, Arundel Street, Sheffield’;  a stamp ‘Monumental Cutlers’ Co, Sheffield’; and another stamp ‘MCC’.  These were registered in 1868.  In 1871, Wright retired and Frederick Wiebusch became partner as the company’s manager.  Wiebusch was a well-known hardware merchant, who was based in New York, but came from Germany.  With Ernst Hilger, he had founded Wiebusch & Hilger in America in 1864.  Monumental had freehold premises in Arundel Lane (according to a newspaper, ‘near top of steps to Pond Street’).   

In 1874, however, Penniman and Wiebusch fell out and the business was sold (Sheffield Independent, 29 January 1876).  T. C. Hill claimed the Monumental trade marks, but was defeated in court (Sheffield Independent, 25 January 1876).  In 1876, Wiebusch bought Eyre, Ward & Co to manufacture cutlery for export to America.   After this idea was abandoned (apparently because of the tariff), in 1879 Wiebusch became involved in transferring Eyre, Ward’s cutlers to America (Sheffield Independent, 1 September 1879).
