The quintant has a black-lacquered alloy diamond-pattern frame, with a wooden handle. The pressure clamp and worm screw are positioned on the back of the index arm with a white plastic micrometer drum. The instrument has no shades. The round index glass is adjusted by a screw and on the round horizon glass by capped capstan screws.

Attached to the quintant is a non-adjustable threaded telescope bracket. The leather covered telescope is 93 mm in length with a large objective lens and an erect image. Several unidentified parts are missing and one foot of the frame is broken.

The instrument has an alloy scale from -5° to 160° by 1°, measuring to 148°. Micrometer to 1 arcminute.

The quintant is contained in a square fitted wooden box, with a Huson certificate of examination in the lid, dated 17 November 1947.
