However, in 1902 the Heavy Battery Committee was formed comprising officers experienced with heavy and siege artillery in South Africa and presided over by Colonel Perrott who had commanded the Siege Train there. In early 1903 their first report dismissed the 4.7 inch (120 mm, used in South Africa) and the 30 pounder (used in India) from further consideration because they lacked firepower. Of the three trial guns they accepted the Armstrong design but rejected all three carriage designs. New designs were sought that were easier for detachments to use. 1904 trials with a new design, including both horse and mechanised towing, resulted in further changes but in 1905 the design for the BL 60 pounder was accepted, although it was still a half ton over the target weight.
