I was curious about one aspect of the report.  And that is that it says:

“Tests of the armor were made with the A.P.X. bullet; 40mm plates were not penetrated ; on the other hand the sides, the rear and the sighting plates were cleanly pierced.”

I asked around to see if anyone had any idea what an "A.P.X. bullet" is.  The best answer came from tanks encyclopedia

The comment from the TE moderator is:

I did some digging and I think I’ve got this one figured out, I think the APX bullets in question are British .303.
All British .303 casings were marked with a headstamp indicating the manufacturer and the type/variant of ammunition and/or propellant loaded into the case.
According to this list of manufacturer designations APX stands for ‘Atelier de Construction de Puteaux’, a french munitions factory known to have produced .303 ammunition, including Armour Piercing ammunition.

Based on the date that Mephisto was captured (April 1918) and on information presented in B.A Temple’s ‘World War 1 Armaments and the .303 British Cartridge’ I think its likely the APX bullets in question were MKVIIF AP rounds manufactured by APX, although depending on the date it is possible they were using MKVIIW AP bullets which were introduced later in 1918
