 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.Attributing this date to the Whm Mswt would create enormous problems for his own reconstruction of Egyptian history since West Theban graffito No.1393 forms part of a whole corpus of sources which Kitchen would never be willing to ascribe to the Whm Mswt since this would upset his whole chronology for the period.
