Fine example of a mid 19th Century Surveyor's compass. The compass itself is contained within its original mahogany box. The underside of which has an attachment for fixing to a pole or tripod, allowing the instrument to be set up and used in the field. The box opens to reveal the silvered face of the compass with decorated dial bearing the makers name "J.Bakewell. Birm'm". It has brass twin folding sighting vanes which open up at either end of the compass and fold away into recesses in the lid of the box. The compass also has a small brass button which, when pushed, locks the directional arrow in place.
