The Archaeological North Arrow is used in photographs to show both orientation as well as metric scale (10 cm, 10 one cm, and 1 five cm) in unit excavations. In other words, this is used to show the size and orientations of archaeological photographs.
v1 had an arrow tip 4 cm in length, so v2 has corrected to the proper 5cm.
The accuracy of the scale is within 0.3 mm and with some printer calibration, you can probably improve the accuracy.
