SASR Don Barnby compass

Wrist compass : Trooper D R Barnby, 2 Squadron, Special Air Service Regiment.
Description: Wrist mounted magnetic compass, finished in medium green aluminium and fitted with a worn olive green nylon wrist strap. The compass has degrees etched into the edge of the rotating dial and mils indicators every 10 mils etched into the body. A small arrow is etched into the top of the compass body, next to the wrist strap. An index pointer consisting of a pair of 2 mm high vertical lines, separated by a small 1 mm diameter dot are stamped into the rotating dial. An orienting arrow and parallel orienting lines, marked in red, are fitted to the base of the compass on a rotating housing.

The wrist strap has seven 2 mm diameter metal bounded holes centrally placed for adjusting the size. An indent with remnants of an unknown blue-green substance (possibly verdigris) is on the fourth hole. This indent corresponds with the wrist band metal buckle. The wrist band is fitted with a pair of horizontally arranged 5 mm diameter bands for securing the excess wrist band length. One of these horizontal bands is adjustable along the wrist band and the other, in a lesser condition, is stitched to the buckle arrangement.
History / Summary

Infantry and Special Forces troops on operations, need to carry a wide range of equipment such as navigational aids to successfully conduct their patrols. It is critical that these objects are as light and as compact as possible to save valuable space and weight. This commercially available self wrist compass is an example of this attitude; recent advice notes that these Silva compasses were purchased and supplied by the the American CISO (Counter Insurgency Support Office).
