The first artillery originally designed in Great Britain. Development started in 1923. The prototype was built on the basis of the Vickers Medium Mark II in 1925. A few prototypes were manufactured, and underwent trials starting in 1925. The project was canceled in 1928 due to lack of interest by the British government.
