Victorian Lead Designations
Many old pencil makers such as Mordan, Baker and others and especially in England and Europe used a letter designation to indicate the diameter of the lead used. There was no standard for this, so it's always best to try and spec out your lead diameter with an electronic micrometer or calliper.
AM = 1.5mm
H = 0.80mm
