Very attractive silver double-sided transparent compass fob or pendant by Francis Barker c.1900 Silver 1" square transparent watch fob or pendant having double-sided peripheral frosted yellow scales open to the centre and enclosed by two bevelled glasses contained within a brass bezel. Scales hand decorated with cardinals in black and intercardinals in red, yellow frosted reflector ring to both sides. Delicately set blue and silver arrow, with bearings in the upper and lower glass, blue indicating north. The compass in a decorative silver surround with bow set to corner, indecipherable hallmarks. The compass swinging freely, finding north easily. The glasses with very light surface scratches not visible to the naked eye, the silver surround in generally very good antique condition. This very high quality compass, with its needle suspended between the two glasses, is unsigned but the work of Francis Barker, the preeminent maker of compasses at that time.
