A rare pocket compass with clinometer by Francis Barker for Troughton & Simms c1900

Antique pocket compass having 1⅝” silvered and die-struck quadrant dial with cardinals and intercardinals, stations at each 10°, divided to 2°, and decorative compass centre. Polished steel bar needle with jewelled suspension and swinging clinometer hand under bevelled glass. Lacquered brass case of conventional pocket watch form with stand to bottom forming the level for the clinometer. Transit lock within suspension ring. 

All contained within its original leather over wood, imperial purple velvet and silk lined case. Snap closure on a button release.

Condition: Crisp overall. The lacquered brass case retaining much of its original finish, losses commensurate with age and use, the dial clean, the glass with a few very light marks. Leather case with some marks and signs of age to verso, otherwise with good colour, the linings vibrant. Compass quickly and easily finds North. Locking mechanism works perfectly.

Comments: This pocket compass with clinometer was manufactured by Francis Barker, the preeminent maker of compasses of the day, for retail by others. Very scarce, only three others of this form have been seen.

One for the collector.
