Several Newboulds were involved in the manufacture of cutlery in the Eyre Street / Eyre Lane area (see Standfield, Newbould & Baildon).  Newbould Bros was launched in the early 1850s by John (1812-1888), William (1814-1873), and George Newbould (1818-1877).  They were the sons of William Newbould, a cutler, and his wife, Frances.  Their firm was located in Eyre Lane and manufactured table cutlery.  In 1858, this partnership was dissolved, after George Newbould left to form his own company.  This resulted in the formation of Newbould Bros & Dickenson, which involved Robert Dickenson (spelled Dickinson in advertisements), William Newbould, and John Newbould.  The firm manufactured or sold from its premises in Eyre Street and Arundel Works, Arundel Street, the usual range of table and spring knives, scissors, and Bowies. 

The Dickenson period proved short-lived and the partnership was dissolved in 1860.  By 1862, Newbould Bros was again listed in directories, operating in Eyre Lane.  The firm was listed as a Bowie maker in 1865.  William Newbould was probably the senior partner, though by the mid-1860s he seems to have abandoned cutlery to run The Old Blue Bell Inn in the High Street.  Newbould Bros became defunct and John Newbould established his own enterprise.
