This is a fully working piece of kit.
It has a white face marked on the top ‘UNIT CLINOMETER’ and on its lower side ‘Lilley & Gillie North Shields England’.
The face is split in two with red numerals in red on the Port (left side) and green numerals on the Starboard (right side).
The case of the piece is made of brass.
The face is 19 cm in diameter, 21 cm in the brass edges are counted and the back end diameter is 26 cm.
The piece is in very good condition with a bit of wear on the numbers.
It works just fine.
