I'm looking for illustrations of this French naval round designed for a fully automatic AA gun, which was never adopted for service but did see action in 1940 while on trials on the Amiens.

Ideally I'd like factory scale drawings of the case and projectiles, but anything will do!

(In case any of you are wondering why I've been asking for detailed information about lots of rounds, it's because I'm rewriting my 2000 book Rapid Fire and want to get as much accurate data as I can on automatic cannon 20-57mm and their ammo - the ammo section will be greatly expanded and might even form a separate volume).
