Ammunition.—3,500 rounds with each gun; 6,000 with regimental reserve; 10,000 with brigade ammunition column.
Mounting.—There are five English patterns of tripods in use and one Indian. Marks I. and II. English pattern and the Indian pattern are exceedingly clumsy, and have been largely replaced by Marks III., III.A, and IV. Mark III. weighs 49 lb., and consists of a crosshead and pivot mounted on three legs with a saddle for firer, and has elevating and traversing gears. A traverse of 25 degrees can be obtained. The two front legs of the tripod are pivoted in sockets and secured by wing nuts, and can be splayed to lower the gear, and fold up for transport. The legs are fitted with shoes to steady the mounting by gripping the ground. When firing, the ammunition box is placed on the ground on the right side of the ground.
On the pack-saddle the gun and tripod are carried on either side of the saddle on hooks and secured by straps. The tool box is carried on the top of the saddle. With this mounting 4,000 rounds of ammunition are carried in eight boxes, four on each side of the ammunition pack-saddle on a second animal.
Mark III.A tripod weighs 56 lb., and differs from Mark III. as follows:
1. The pivot has a bearing surface to support the rear end of crosshead arm.
2. The hand nut of elevating gear is formed with four small radial holes.
