…; Ministerie van Marine (Department of the Navy), The Hague, 1819;¹¹HNA 2.12.01 Min. Marine, Exh. 19/10/1819 N22. transferred to the museum, 1883

Object number: NG-MC-878

Compass in binnacle with a pyramid-shaped top and a compass card in a separate box.

The binnacle has a door in the front. All the faces of the top are made of glass. Two of them can be sealed off with a copper plate, while on the third a similar plate with a lamp holder is placed. The lamp is missing. The copper compass bowl hangs in gimbals and has a lead weight beneath. The pivot has a head made of ruby. The compass card has a brass cap with the dab for the pivot. The turning of the card is facilitated by the materials used, while the large area of friction of the ruby simultaneously reduces the tilting movements.

Obreen incorrectly dates this compass to 1825.²²J.M. Obreen, Catalogus der verzameling modellen van het Departement van Marine, The Hague 1858, no. 878. The binnacle and compass card were sent to the Navy Model Room by the Navy dockyard in Rotterdam in 1819, as part of a collection of objects from the United Kingdom.³³HNA 2.12.01 Min.
