Rare British WW II Air Ministry Miniature Nautical Sextant

About the Item

Here is a gem of a high quality British Air Ministry sextant from WW II. It is the second one we've discovered in this remarkably fine condition. A micro-mini tiny sextant that has a radius of arc of only 3 1/2 inches, but has large size mirrors and shades, full size micrometer drum, of regular size sextant. Every thing is designed to make this instrument perform like a full size sextant.

There are no maker's marks, but it carries the serial number 35017 on its arc. Both Heath and Hughes made these instruments for the Air Ministry, and since this one is slightly different from the Heath we recently sold, we will attribute it to Hughes. Both were one of Britain's Class ?A? sextant makers. Like the Heath, the index arm imprint reads:
Royal Crown
AM
REF No 6B/177

AIR MINISTRY DESIGN: The Royal Crown and AM marks indicate this sextant was made for the military which accounts for its exceptional quality. The AM stands for Air Ministry. Marine sextants of this type were used on seaplanes for taking anchor bearings and also other calculations such as amplitudes of the sun and distance off angles when on the water.
