A very fine and large pair of 17th century brass and steel single-handed navigational dividers. Constructed with a five leaf friction joint with unusually large globe head, at 7 ¾ inches in length these are a good size for such an instrument. Historically used for navigation, they are similar to the pair depicted in the 1653 portrait of Elias Allen, see final image.

Similar examples are in the London Science Museum collection:
