The illustrations posted by Qrt.S, as far as I'm aware, are not connected with Joseph Wolstenholme. The top one, at least, refers to Wilfred Henry Wolstenholme who was in business as
Wolstenholme & MacLaurin (Wilfred Henry Wolstenholme, Henry MacLaurin, George MacLaurin) as Electro-platers until April 1874. Following the break up of that partnership he likely had a period on his own before forming the business
Wolstenholme & Biggin (Wilfred Henry Wolstenholme, Henry Biggin, Arthur Wolstenholme) Electro-Platers and Britannia Metal Manufacturers, that partnership was dissolved in November 1879.
As Burnisherboy has stated Joseph Wolstenholme's business was founded in 1821:

Joseph Wolstenholme - Sheffield - 1837

Joseph Wolstenholme - Sheffield - 1852
