H. Hughes and Son Mk VIII Sextant


Standard RAF issue in the 30's and still used for training purposes after the MK IX had been introduced in 1940.

Note the pencil, used to achieve an average indication as many American Instruments did.

The photo above, from a wartime book, shows apparently, Pilots being trained in sextant use.

Whilst I am not certain that the German firm Plath did actually copy this instrument, there are remarkable similarities in their instrument, even down to the helix with a cam follower for the index mirror. I have not opened mine yet but will have to eventually because of a lack of bubble. My Plath Gyro Sextant I have had mostly in pieces and think I fully understand the function of its parts.
