RAF Periscoptic Sextant Mk. 11A, model no. 6B/434-3796

This example comes complete with a fitted transit case, appears to date from 1961 and was manufactured by Kelvin Hughes. Complete with cables. These instruments carried a 3 volt system for the lamp and a 24 volt system for the heater. They were used on pressurised aircraft such as the RAF V Bomber Force and enabled the navigator to establish the aircraft's true position when other navigation aids were unavailable. In good issued condition although we cannot guarantee the instrument is in working order or air worthy! Case measures 18" (46cm)
