E. B. Wilson and Company

Many of the maker's plates, however, retained the name "The Railway Foundry, Leeds".

Fenton's boiler designs were particularly successful, and the company's products acquired a reputation for workmanship and reliability.

Originally an apprentice at Fenton, Murray and Jackson and later at Shepherd and Todd, David Joy was their Chief Draughtsman and was tasked with designing a new engine for the London and Brighton Railway.

Joy would appear to have produced the drawings, but Fenton would have had to approve them, and the success of the engine undoubtedly owed much to the latter's boilers, which were working at the unprecedented pressure of 120psi.

They charged a premium for any variations, although the size of the engines gradually became larger.
