Learned something new today (or at least re-learned it in the case that I knew it once and forgot). In older maps, a full North Arrow is intended to mean true North while a half North Arrow may indicate magnetic north with a east or west declination depending on which side the arrow is on. Everything we do here at work is true North / Geodetic North / Grid North so I guess I haven't thought about the north arrow in light of indicating declination. Luckily we our typical north arrow looks like this...
so it shouldn't matter much.
