The Greek alphabet and number system is almost related to the first rod except for the extra entry 𓁹𓌴𓈖𓏏𓆑 between 90 and 100. This is a general problem: we have 27 numbers but 28 days! The second rod is from a side branch in the development of the alphabet dissimilar to greek. The first sifted letters might be explainable, the 𓅝 𓅮 part much less so.

Halaham

The 28 cubit on old Egyptian measuring rods were previously assumed to represent or connect to some form of ancient Alphabet.

It is weakly compatible with the 𓀠 𓏲 𓇓 𓈖 Harashamun form of the Halaham :
