Why do you persist in writing Khnum Khuf?
It is Khnum Khfw.
The cartouches in the Arbuthnot and Wellington chambers are not inscribed with the name Khnum Khuf.
They spell the name Khnum Khfw.
On the lateral inscription the viper "f" is BEFORE the quail chick "w".
That's F followed by W when read from right to left as it was intended to be read when written in this way.
Give it a rest, why don't you? You are flogging a dead horse with this argument.
