c.1740 Messrs Perry set up a japanning business 
1835 Richard Perry, Son and Co, japanners, of 7 Queen St
1842 Richard Perry, Son and Co, tinplate workers, of Temple St
1872 Japanners, of Temple St, Wolverhampton
1880 Japanners and tin plate workers, of Temple St, Wolverhampton
However, there is a different story in W. H. Jones's book "The Story of Japan, Tin-Plate Working and Bicycle and Galvanising Trades in Wolverhampton" (1900):
Richard Perry, Sons and Co, set up by Richard Perry and his son George, was in Brick-kiln Street. Father and son had both been japanners in the Old Hall works and struck out on their own. Jones gives no further information about this firm until we find his reference to Edward Perry's nephews, the Lees Brothers, carrying on the firm of Richard Perry & Sons.
On Edward Perry's death they acquired his business, possibly by inheritance. It was, almost certainly, a much larger concern. It therefore seems that the company known as Richard Perry, Sons & Co, was a direct continuation of Richard Perry and George Perry's firm and incorporated Edward Perry's business.
It is not clear what is the basis for Jones' information since no references are included in the extract quoted.
