"These works, in Sutherland Road, were established by Benjamin Shirley of Bangor, Wales, on the day of the marriage of H.R.H. the Prince of Wales - 10th march 1863 - and were, in honour of that event, named the Prince of Wales's Works.

They were carried on for a time by Benjamin Shirley and Walter Freeman under the style of Shirley & Freeman (late of the Sheridan Works). On the death of the former, in 1864, Titus Hammersley became a partner with Mr. Freeman.
In 1866, Edward Asbury joined the firm, which carried on as Hammersley, Freeman & Co.

In 1870, Mr. Freeman retired from the concern, and the style at that time was Hammersley & Asbury. After the death of Hammersley, in 1875, the works were continued by Mr. Asbury alone under the style of Edward Asbury  Co.

The goods produced were china, tea coffee, dessert, and trinket services - a special feature being articles bearing local views in colour, for sale at watering-place - principally for the home markets; but goods were also shipped to Australia and the United States.

The mark used was the prince of Wales' feathers, with the letters H & A in a garter, or A & Co.

Edward Asbury & Co. continued to 1925."
