>who knows what might be found in the Cairo museum<

Interestingly writing in 1929 Clarke & Engelback comment that:

"...the Cairo Museum possesses but one example, which might conceivably have been used by masons, namely the very rough, ill-divided rod found in the tomb of Sennutem at Thebes."

They go on to excluded the examples from the tomb of Tutankhamun as they hadn't been fully described at that time.

I'm aware of four complete cubit rods on display in Cairo Museum now along with some other fragments, again excluding the Tutankhamun ones. Who knows what else they've got in the basement though.
