This is marked "BENJAMIN RITTENHOUSE" and seems to be a typical Benjamin Rittenhouse compass from the period 1785–1796. The face is beautifully engraved, and the graduations on the needle ring are done with great accuracy. The socket joint can be adjusted so that the compass is held rigidly in place. The signature is off–center, however, with scant room for the final E.
