A very good large brass cased antique surveying barometer by Fraser, London c1810

Georgian Surveying Compass by Fraser c1810


Antique surveying compass having 4″ hand engraved and decorated quadrant dial showing cardinals and intercardinals, the upper part marked “Fraser, London.” Outer stepped ring displaying 0 – 360 degrees, divided to 1 degree increments. Blued steel bar needle on jewelled pivot, transit lock. Original flat glass contained within spun brass bezel forming side of case. Heavy brass base with fixing screws, push-fit spun brass lid.

Condition: In crisp original condition, the glass unmarked except for two very small firing flaws demonstrating its originality, the bar needle swinging freely and finding north easily, the lid-activated transit lock working well. The brass case undented, with patina and a few small marks commensurate with age and use, the lid fitting smoothly and snugly.

Comments: Although surveying compasses with this style of dial are not uncommon, it is unusual to find one of these surveyor’s compasses with a simple round base, and not one formed with integrated fixing lugs or plates for use with a circumferentor. This example has two spare screwholes in the base to allow for fixing to a circumferentor, but this compass may also be used as a straightforward travel compass.

A substantial and very attractive antique surveying compass.
