Blomefield design
Thomas Blomefield became Inspector of Artillery, in 1780. Between 1782 and 1785 his department carried out a general reproof of ordnance, he rejected nearly half of them. In 1787 cast iron guns of Blomefield's own design were made. He made three significant alterations to the Armstrong design. Firstly, the breech was made more rounded, eliminating the prominent mouldings. Secondly, the first reinforce was made almost cylindrical, the second reinforce was strongly tapered and the chase strengthened. Thirdly, a ring was added to the cascable which allowed free movement of the breech ropes, used to restrict the gun's recoil aboard ship. This free movement allowed the gun to be trained at an angle to the side of the ship and still have effective recoil restraint.
