In A Nutshell Antiques and Interiors has dated this piece to the Edwardian era.
The compass sits between two brass uprights which are mounted to a good quality wooden base.

It is a very well made and heavy duty piece of equipment and the ring around the face of the compass is stamped "PATT. 160110. No.25A/62. A/R/65".
It is in good condition for its age and the compass itself is in working order and is, as far as I can tell, fairly accurate. It moves freely on the gimbal mount. The liquid has discoloured over time and is slightly darker than it should be, slightly obscuring the face of the compass but it is still readable and usable. There are some knocks and marks around the casing and the uprights supporting the compass look like they've been re-soldered at some point but overall the whole piece displays very nicely.

Approximate Measurements :
Base : 12” x 6” (30 cm x 15 cm)
Diameter of Compass : 5” (12.5 cm)
The best description comes from the photos so please look at them all carefully and if you have any questions just ask.
