1877 Mr. James Shaw and some associates acquired the extensive establishment of the Governor and Company of Copper Miners in England, better known as the Cwm Avon Ironworks.
"This famous company was incorporated by Royal Charter in 1691, and went into liquidation in July, 1876, having succumbed to the storm which wrecked so many other concerns engaged in the iron-trade. It is well known that their great works had cost this ancient Corporation over a million and a quarter of money. Mr. Shaw worked this property for some years with remarkable success, and at a later date, formed the property into a limited liability company, which has since gone into liquidation."[1]
