This binnacle pattern was developed by the makers Kelvin, Bottomley & Baird for commercial shipping, although the design followed Admiratly patterns quite closely. The binnacle has a wooden pedestal and a brass hood. Attached to the pedestal are a brass case for a Flinders bar and two soft iron spheres. These helped to correct the deviation of the compass caused by the iron in the ship. The binnacle hood carries a mirror so that the reflection of the compass card can be easily read while steering. There are also two lamp holders to provide additional lighting when needed.

The liquid compass can be lit from below when used at night. The compass card is marked in degrees and quarter points.
