Rich,

Star 'clocks' are not star maps - the interior of the MK coffin lids have star 'tables'.

They also have depictions of Nut (the sky), Sah (Orion) and Sopdet (Sirius) in the southern sky, and Mesekhtiu, the large distinctive 7-star asterism in Ursa Major known as the 'Plough' / 'Big Dipper' in the northern sky, but again, I would hesitate to call these maps, but rather depictions of the personifications of the sky, Orion, Sirius and the Plough.
