EXTREMELY RARE
F. BARKER & SON
SMALL POCKET GIMBALS COMPASS
FULLY SERVICED
VERY GOOD CONDITION


This unusually small model is unsigned but carries the mark "PAT N° 110002/16, which was granted to F. Barker & Son in 1916 with regard to its development of liquid prismatic compasses

The compass has been cleaned and serviced with new seals and fluid and is in excellent working condition. The bowl and gimbals are chromed brass.

The original leather case is in perfect condition with no damage at all to the leather or stitching

To use the compass you open the leather lid, then pull the support collar upwards, releasing the gimbals. To close simply push the collar back down into the leather (brass lined) base, locking the gimbals, and close the lid - the patent bubble trap is used in accordance with the instructions in the CAVEAT below

DIMENSIONS:
Case closed: Diameter 71mm Thickness 36mm
Compass bowl diameter: 45mm
Compass card diameter: 29mm
Overall weight: 240g

CAVEAT: This compass is old and will always have a small bubble. This is unavoidable, but the manufacturer included a bubble trap to remove the bubble from view by inverting the compass and turning it slowly the right way up. Also, due to the nature of the very old and still original bowl lining paint, (which is still in very good condition) it is possible that small particles may appear over time in the fluid when the compass is moved or inverted, but the particles would be few and would always settle to the bottom of the bowl. This possibility could have been avoided by re-lining the bowl, but I decided that for this compass the occasional possible particle appearing suspended in the fluid would be a small price to pay for maintaining the compass's original lining, especially as re-lining the bowl would have caused the loss of the original Patent Number
