cTh is a eTe?

[Grove]

I’m sure there are a number of cthh extended benches, but also can’t exclude any ea or efe ‘spellings’ either. As far as the difference between the glyphs c e and h, it might come down to how the horizontal line is applied. Does the scribe write down a pair of c’s and then the line to join them, do they write the horizontal and second c in one stroke?
