Pic related. The one above the RAY GUN is the final anode. The one below the Final anode is the electron gun.
Are these things connected by some sort of internal glass coating of the tube? because the final anode is not the same as that thing coming out of the electron gun. And I found about this specific thing nowhere on the internet, never seen an electron gun drawing that included this metal thing that is clearly coming out of the electron gun and is not the final anode itself (note: even inside the glass tube they are pretty distant from each other).
