This is a Small Nikon Pillar Stand with Rack & Pinion Adjustments.

This is an elegant compact pillar stand that appears to have been manufactured by Nikon, although the Nikon logo or name does not appear anywhere on the stand itself only on the focus drive. The stand weighs just shy of 30 pounds with a 10 inch diameter base.

The vertical pillar is 11 inches tall and 28mm in diameter (overall height with the base is 13 inches). With the clamping support ring and the cross-bar holder installed, the total available vertical excursion is 7 inches.

The horizontal boom has a travel of approximately 4 inches via the cross block, which is keyed to prevent the boom from rotating. There is an additional 2 inches of rack & pinion motion at the end of the boom. Attached to the boom is a post with adjustable inclination. The post is 24.45mm in diameter and 77.5mm long not including the threaded cap at the bottom of the post.

On the underside of the rack & pinion mechanism are two threaded bores, both of which are empty. It appears that one would have held a clamping knob for the boom extension, and the other would have served as a guide pin for a channel in the bottom of the extension. Presently the boom is free to tip slightly from side-to-side, although the rack prevents further motion.

The focusing yoke is of more recent construction. It uses a dovetailed rack & pinion motion with a total travel of 40mm. The inside diameter of the yoke is 62mm. It is branded Nikon.

Overall condition of the stand is excellent. All the motions work very well with the exception of the missing guide screw and clamp screw mentioned above. There are department asset identifications etched into the pillar base and the cross block, as well as the focus drive, but they are neatly done (see photos).
