20x110 Hispano, French either Swiss?

[pzgr40]

I just obtained this 20X110 Hispano shell, it has a tracer self destruct, the explosives room ends 5 mm above the driving belt, but the most eyecatching feature is the fuze of which the top 5mm is steel made, as the rest is brass. The fuze ia assembled with a base screw, and uses a firing pin.
Who can give me a type designation and a cutaway drawing of this projectile. I Suspect it to be French either Swiss, but I may be wrong.

The internal parts of the fuze......
So, the fuze uses the floating firing pin principle.

After cutting the projectile, doubt creeps in. The rounded explosives chamber, the whole design looks more and more Oerlikon.....

Measure the diameter below the drive band and the width of the band.
Oerlikon is 18.8mm diameter and 4mm wide. Hispano is 19.4mm diameter and 5mm wide drive band

19.4 just below the driving band and the driving band is 5mm wide. So Hispano....
But what country... Swiss, France, or another country

I find that UK and USA Hispano and Oe fuzes have the same threads even if the internals are different.
Maybe someone screwed an OE fuze onto your Hispano case?Just a thought.

you may be right. on the other hand , the internal design is not really USA or UK
