In 2011 at least one pallet load of the EX RAF, "Sextants Periscopic Mk 2" had apeared on the surplus market and sometimes they pop up on EBay. I have a few of them and very immpresive they are. What a shame they are so heavy. Technically they are at least a match for the Kollsman, the American version, and if, as me, you have a wartime Mk IX you will see the obvious development into what became a standard piece of V Bomber equipment. I have been able to get hold of some of the original paperwork for these instruments and have tidied up and printed them as an A5 booklet of service and technical papers with operating instructions and circuit diagrams which I am offering here. The models covered are 2, 2A, 2B and 2T, the polar regions version which has a polarising filter. The aircraft skin mount is also covered in some detail. You may have noticed you cannot see a bubble, well, some are actually pendulous types like the later Kollsmans and all models will be invisible untill 3 volts is supplied to the lighting circuit. There is a 3 pin plug which has neg., +3V and  +28V for the heaters, all is explained in the booklet. 37 Pages, Black+White with 27  illustrations.. Maybe all you need to get yours going?

I have similar info on the Mk1.
