Hill’s note places this “On a Stone No. 4. Southern Side”, but his numbering is obscure. The smaller stroke at bottom seems not to be part of the number, so a number 5, matching Rowe’s Cheops 75. Hill recorded one Perring missed.
Creighton’s 2nd drawing after Hill:
The conflict in evidence concerns the character following the ten (). Birch followed Perring’s drawing (as reproduced in the larger lithograph) and read the character as a ligature writing of III—but in this case the number would be 13, not 23.
Some strong clues here.
