It looks like there are at least two more, at 7:00 and 8:30. The one at 10:00 also appears to branch to the outer leaf of second leaf cluster. The crack from the rim through OD to the top of the cross continues across the top, down across the right arm, through the curl and then through the first two leaf clusters on the right. It may also join up with the crack through T and the one at 2:45.
