Physical Description

The barrel consists of an autofrettaged loose liner, jacket, breech mechanism, oil reservoir and screwed collar. The loose liner known as the rifled A tube could be removed and replaced when worn. The breech mechanism is a single action Asbury breech of the vertical sliding type with a mechanical firing lock. The breech utilised a stepped, interrupted screw known as the Welin pattern to ensure that it could be operated in one smooth movement. The Mark II carriage of the box trail type comprised a hydraulic buffer upon which the barrel was mounted with a hydropneumatic recuperator that all worked within a cradle box that moved with the gun box after firing. A circular platform is fitted upon which the gun can be mounted which enables an easy all-round traverse. The gun is a high velocity, comparatively long range, weapon using propellant charges of different weights so that the relatively flat trajectory obtained with the higher charges can be altered into one with a steep angle of descent.
