Roorkee Instruments India Top Grade Gilbert & Son London Sundial Compass/Perfectly Calibrated Compass
The top of the sundial is hinged and a curved scale is used to set your local latitude angle. The magnetic compass permits the sundial to be oriented North. During transport, the needle lift mechanism of the compass is engaged to protect the compass's jeweled bearing. The sundial can be accurately leveled by three adjustable legs. The local time can be determined by looking at the sun's shadow cast by the vane of the sundial. For compact storage the top of the sundial can lay down flat.
