Azimuth compass in gimbals in a wooden box.

The copper compass kettle is weighted with lead inside. The compass card is suspended in a rather peculiar way: a separate set of gimbals is mounted in the bowl, in which a thick axle with a weight hangs like a pendulum. The top of this axle is hollowed out and has a precious stone in the middle. The compass card has a hole in the middle with a bridge across it with the pivot pointing downwards, standing on the precious stone.

Because of the hole in the card, the use of a single compass needle was impossible; this was solved by the use of two parallel needles. The compass card is balanced with red sealing wax beneath. Box and cover bear a stamp of an anchor in a circle.

This compass was bought by the Department of the Navy in Copenhagen in 1820.²²J.M. Obreen, Catalogus der verzameling modellen van het Departement van Marine, The Hague 1858, no. 876.
