 A prize of 50 guineas (£52.50) was offered, and several models were submitted.The committee enlisted the help of John Wilkinson and the inventor and engineer James Watt to judge the designs, and were more generous with prizes than they had advertised, since John Lowdon of Snedshill and Henry Williams of Ketley both received £50, and several consolation prizes were also awarded.Lowden had been appointed as surveyor before the competition was completed, and supervised the work.
