These look like mold ejection marks.

Here are the marks on my MK 1, 2 & 4 IAB's. Notice the marks after the numerals on the #4 and #2 IABs. At first glance I used to think that these were part of the logo mark, but now can see that they are actually some kind of ejection marks, although they are very small. The #1 IAB doesn't have one, or else it is located slightly higher and is not as clear as the others.

I raise the point because most of the MK IABs I have seen have similar looking marks. Also, it is a strange location for an ejection mark. Opinions?
