Taking another look at these chamber markings ,

Here are some pics taken by a Colette Dowel,
[www.robertschoch.net]

My reason for putting these pics together was to see if one can notice any difference in the pigmentation of the other markings as opposed to the so called Khufu cartouche , and as the pics were taken through the same lens one should expect similar end rendering of colour.
There does seem to be very little difference in their pigmentation, albeit the Khufu Cartouche seems a little brighter or shiny , but that may explained by people wiping over it to clean it for photographic purposes .
But what of the style of the Khufu cartouche compared to the other markings, well as i dont know what the other markings mean i can only offer my personal view that the Khufu cartouche writer was not the writer of the other markings.









Hope thats not further muddying the waters.
