This object I achieve by combining with In Fig. 1, and with portions in greater detail a mount, including a pedestal, a column rotatable in Fig. 6, appears the mount M of a gun G. The and vertically movable therein and a trunnion mount includes a vertical pedestal Hi, arranged bracket ?xed to the column, and a gun trun vaxially in which is a cylinder l2, both being nioned upon the bracket, a cam or other stop secured to a base Hi.
