The attractive silvered dial is signed''J.41 Bull St, Birm'n and has a stepped outer chapter ring with a 0-360 degrees scale in one degree increments. He is recorded as working at the 41 Bull St address between 1850 to 1856.
A substantial compass weighing just under 800 grams and measuring 5 ½ (135mm) square, it's visually very impressive, despite the fact that it's had noticeable repair work on the lid and hinge, see photos. In good working order including the transit lock, the lid is designed to lift off and it also comes with a removable tripod adapter.Please study the photos as they are part of the description, and I will be happy to answer any questions if I can.
