This item is a Klinger Model SK Gimbal Mount for optics of 51mm diameter. These gimbals are somewhat more sensitive for mirror adjustment than the SL type gimbals. This particular mount is unusual in that there are two methods for securing optics or mirrors. The first method is identical to that found in the more common SL type gimbal mounts. There is a spring-loaded ring with a pair of threaded posts to accommodate lenses or mirrors with edge thicknesses of up to 12mm. There is a recess in the gimbal mount machined for 51mm diameter lenses, with three precision bearing points that are perfectly matched to the common tilting planes for azimuth and elevation. The securing ring is likewise fitted with the three bearing points. The two posts are slightly asymmetrical in order to allow easier exchange of the components via the larger of the openings.

The second mode of mounting is for larger-than-specified 51mm mirrors. The recess on the opposite side of the ring mount is stepped and will accommodate mirrors in several sizes up to 63mm in diameter. There are three spring-loaded arms that secure the mirror into the appropriate recess. By reversing the mirrors so they face away from the mounting surface it is possible to use very steep grazing reflection angles.

Height & width of support� 100mm
Thickness of support � 26mm (30mm including gimbal plate)
Clear aperture � 48mm
Travel range (elevation and azimuth) � plus or minus 1.5 degrees
Minimum thickness for ring-mounting � 10mm.

This particular mount is equipped with the Type BD differential micrometers for both the azimuth and elevation. These micrometers have both a course and a fine motion that may be imparted to the gimbal. Sensitivity of the differential fine drive is approximately 10 times as great as that of the standard micrometers.

The mounts are in excellent condition. They do not come with any mounting plates or bases. Klinger part number (with BD micrometers) is 133 315.
