As I drifted off to sleep last night, it occured to me that my "solution" couldn't possibly be correct: if "directions" were "reversed" in the Southern hemisphere, then such a compass wouldn't be such a rarity.
I then became convinced (because of the Pilot Training question) that it must be for a 20th C vehicle - a submarine or fighter jet - where the compass had to be viewed as a reflection in a mirror (top & bottom unaffected, but left & right reversed: made perfectly logical sense to me as I drifted off!)
So: Russ was right in #3?
