Seemingly part of terracing wall system includking 5006 and 5007. Related to other orange tufo headers 5123 and 5125. Square blocks rather than full rectangular ones and placed to form orange/grey pattern for aesthetic color effect when viewing terrace wall from the south. Sits as another course of wall 5006. Heavily disturbed presumably by later robbing activity.
