John James, William Caslon I and Baskerville were left by consolidation as the only three representatives of the trade in the country. Caslon had two apprentices in his Sheffield Foundry, Thomas Cottrell and Joseph Jackson. They started a foundry of their own in direct competition to their employer in 1757. In 1759 Jackson entered the Navy leaving Cottrell to carry on alone. Jackson left the navy in 1763 and continued to be employed in Thomas Cottrell, Neveil's court 1759–1785 Foundry for a short time. He commenced business in a separate Foundry with two fellow workman who helped to find the capital 1764 – 1792. When Jackson died in 1792 it was William Caslon I's grandson, William Caslon III who purchased the foundry in Salisbury Square.
