In this post, I did NOT say the other 2 ivories in the scan were part of the Gerhart set.
The scan is 3 ivories given to me.

In the original post, link provided in this post, the story never states they were part of Gerhart's set.
In fact this scan in the original post shows all chips found in the 2003 find.
As you can see the other 2 are not in the scan.
