The limber consisted of a steel frame, two steel chests, wheels, axles and a draft connection for 2 or 4 horses or a tractor unit. The wheels were 60 inch in diameter with 6 inch wide steel tyres and the outer end of the axle arms were equipped with drag washers to assist manual hauling. The vehicle had no brakes.

Mounted onto the chassis were two steel chests. These had flanged corners to allow clearance to the swing of the connector on the carriages when travelling. The chests had lids hinged at the front and were intended to carry stores and equipment for the gun. The left chest carried the sights and attachments together with a number of small tools and one powder charge in a tin box. The right chest carried the clinometer, oil can and other tools and accessories together with one powder charge in a tin box.

Behind each of the chests was a steel bracket that carried one round of ammunition which was carried in a vertical position and held in place with a leather strap.

Suspended below the chassis was a wire net that carried drag ropes and lashings for the gun.

Forward of the steel chests was a board that could accommodate two rifles.

When carrying two shells, the limber weighed 2,240lbs.
