The German Egyptologist Daniel Polz, who discovered this king's tomb in 2001, also studied the same doorjamb and reached a similar conclusion in a 2007 German language book. An association between Nubkheperre Intef and a king Sobekemsaf is also indicated by the discovery of a doorframe fragment by John and Deborah Darnell in the early 1990s which preserved part of an inscription naming a king Intef ahead of a king Sobekemsaf; the hieroglyphic spelling of the king Intef here was that used only by Nubkheperre. Unfortunately, not enough of the inscription was uncovered to reveal the nature of the relationship with any certainty here—or which king Sobekemsaf was intended. Nubkheperre Intef is sometimes referred to as Intef VII, in other sources as Intef VI, and even as Intef V.
