My most baffling gas mask, the French ANP M51

The French/Belgian A.N.P. M51 gas mask/respirator is one of the weirdest gas masks in my collection.
Most gas masks I can decide if they are poorly designed, hit and miss or excellent designs, but this mask is weird. I've owned it for about six years and I can't decide if I like it or not.
The name of the mask is "Appareil Normal de Protection" meaning Normal Protection Device in English. There was two particular models of this the M51 and the slightly improved M53.
The mask is made from a good rubber, but with an awful exhale valve/voice diaphragm which can compromise the protective qualities of the mask, it has a working Tissot system and early plastic lenses, but it also has a weird strap system and no oral-nasal cup.

As explained in the video, I can't decide if I like this mask or not.
