Somewhat related to the recent post on the B-52 Astrotracker (which was a great read), there is an unusual listing on eBay right now for some type of mechanical celetial navigation calculator.
"ANTIQUE CELESTIAL NAVIGATION 3 GAUGE CALCULATOR AZIMUTH DECLINATION LATITUDE"

Does anyone know anything about this strange contraption? The interior photos of the device show what appears to be a mechanical modelling of the navigation triangle.
