 In 2007 Professor Kenneth A.Kitchen argued that the combination of Late Ramesside Letter 41 (undated) with a reference to a Year 12 in West Theban graffito No.1393 (which mentioned the necropolis scribe Ankhefenamun visiting the mountains with the senior scribe Butehamun, Dhutmose's son) likely shows that the Whm Mswt reached a Year 12 or Year 30 proper of Ramesses XI.However, Kitchen's own standard book on the Third Intermediate Period previously attributed the anonymous West Theban graffito No.1393 to the reign of king Smendes and not to the Whm Mswt period.
