The third John Rigby, born in 1829 in Dublin and educated in science at Trinity College, took over in 1858 when William, his father, died. It was this John Rigby who brought the firm to international prominence. In 1865, capitalising on the awards his family's guns had earned at the Great Exhibition in London in 1851 and at the Paris Exhibition of 1855, in 1865 John Rigby opened a store at 72 St James's Street in London's West End. Sometime in the 1890s, Rigby sold his Dublin operations to Trulock &amp; Harriss (keeping, however, his customers in Ireland) and became a bona fide member of the small circle of elite gunmakers who catered for London society.
