UNIQUE ANTIQUE
CHARM ANEROID COMPASS
IN 15ct GOLD MINIATURE HALF HUNTER CASE
BY F BARKER & SON
circa 1880 - 1910


This is one of four of this design known to still exist - two others in gold, and one in a silver case, which is broken and beyond repair

This model was manufactured by F Barker & Son between 1880 and 1910 - it was offered only in silver, 15ct gold or 18ct gold - and it was expensive even then.

This fob charm aneroid / compass is the 15ct gold version with the "keyless" action - a knurled winder inside the bail ring which, when pressed, releases the lid catch, and when rotated causes the altitude chapter ring in the barometer to rotate to zero your altitude or to zero the current atmospheric pressure

I have restored this instrument, which involved the creation of several minor parts and the repair of the sweep indicator (pointer) - The barometer passes the plastic bag test and tracks changes in atmospheric pressure or altitude, though it may not be quite as accurate as a modern barometer

The compass is more for show than functional. If removed from the instrument (it's designed to pop out easily) it works perfectly, but in all these instruments iron components were used in the barometer, and this causes errors in the compass - the compass is designed to be pressed out of the lid and used separately, and in this case it functions perfectly

There are only a couple of tiny dents to the gold case, and the crystals in the compass and the barometer are all original and in excellent condition - the dials have over 95% of their original silvering and are in very good condition - the only "blemish" is the restored circular sweep indicator, but it has been well done and you have to look carefully with a magnifying glass to notice

In all the years I have been dealing with compasses I had only ever seen photographs of one silver version (mentioned above), and two other gold examples in working condition

DIMENSIONS - AS SHOWN IN THE PHOTOGRAPHS BELOW
OVERALL WEIGHT 32 grams

Altitude chapter ring: zero to 5000 feet
Barometer dial: 26 - 31 inches mercury
Open centre dial so you can see the aneroid movement

This is an exceptionally beautiful and rare instrument, gold and glass are difficult to photograph, and the photographs simply do not show its true beauty. It is in museum condition
