A tilt adjustment arrangement (10) comprises a housing (11), an eccentric member (13) and a mounting member (16). The eccentric member (13) is rotatable about the housing bearing axis (18) and mounting member (16) is rotatable about the eccentric bearing axis (19) and provides a mounting for an item such as mirror 21 to be adjusted (20). Rotation of the eccentric member (13) relative to the housing (11) and of the mounting member (16) relative to the eccentric member (13) both change the angular disposition of the mounted item (20) relative to the housing (11). A second eccentric member may be interposed between the eccentric member and the mounting member (figure 2, not shown). The mirror 21 may be part of a gun muzzle reference system (figure 3, not shown). |
