There are two different types of Horn watermarks in the Leicester and Arundel Codices. Representing Group A is Arundel 34-35, and representing Group B is Arundel 146-150. Each Horn is marked with eight points. The watermark should be oriented so that the mouthpiece is on the left and the bell (where the sound exits) is on the right.
Point Locations:
intersection of top of the cord on which the horn is hanging and the vertical chain line bisecting the watermark
top intersection of the two circular portions of the mouthpiece
intersection of the bottom of top loop of the cord on which the horn is hanging and the vertical chain line bisecting the watermark
intersection of left branch of the cord with the horn
intersection of chain line bisecting watermark and the upper edge of horn
intersection of right branch of the cord with the horn
intersection of chain line bisecting watermark and bottom edge of horn
