The 1/2 Scale Compass
This compass faithfully matches the full-size Rittenhouse compass.

This is a working 1/2 scale compass which faithfully matches our full-size Rittenhouse compass, and has the same working parts. The needle is lifted by a small screw, the sights remove, and the compass itself can be unclamped from it's base and rotated or removed. This makes a great gift, perfect for awards or presentations. A brass plaque is affixed for engraving. (Engraving is optional)
