Alex- Regarding "tropic resistance"...that can be a funny kind of catch-all. I suppose that if the standard Soviet sextants were assembled with a grease that would not freeze up in Arctic use, that grease might be unsuitable in the tropics, i.e. migrating too much, so something as slight as the grease might be changed. I've seen the Freiberger (presumably original) grease migrate and stain the "white" enamel, even though it could stiffen horribly in the cold. Dunno, but it certainly would be curious to find out what the Soviet Navy considered "tropical". C&P seems to think black paint is "right" to prevent reflected glare--except for white paint for tropical use. Maybe the color of the sextant?
