Hi all,
My interest in obsolete technology and a bygone era have made me model a
RAF mk9 bubble sextant for FlightGear:

It is easy to add to an aircraft (but I won't say it is easy to use :),
and I made some quick examples that I put together with the archive. It's
not quite appropriate for any of my aircraft in CVS but I'll probably add
it to my ZF balloon.
I'm not sure when this particular model was put in production but I think
a bubble sextant was a common piece of navigational equipment for long
distance aircraft throughout the 1920ies to 1950ies (maybe even 60ies?).
If this instrument is useful for more than one aircraft it might be nice
to put it in Aircraft/Instruments-3d/
(maybe with a more specific directory name than BubbleSextant, though.)
The archive and some documentation is available here:

It could be funny to say that Blackbird, had Celestial navigation.
So, such AC instrument FG development is not so obsolete.
