Diameter 52.25 mm, inner bezel diameter 44 mm, inner depth to bezel 16 mm.
Gilt brass base, with underpainted horn covering. Good unrestored condition.
The horn on the bezel is perfect. On the back the horn is complete, but with a short crack from the edge at 10, and the longer one across the back from 5.
Just 2 pins missing from the back and none from the bezel. The hinge and catch are fine and the case snaps shut nicely.
