Looking at the driving belt of the projectile i'd say a 20x110 Hispano Suiza API on a 20x110 Oerlikon shellcase.

Thanks pzgr40
Difference between the two.
20x110RB has the narrower the band of 20x110 Hispano.
thanks

Ok, so it is an actual Oerlikon API. Diud not know they existed.

The Uk experimented with AP-I,AP-HE and AP-T projectiles for the 20x110RB during the early 40's but none were put into service, the only reference I can find for the red band is the UK late dated MK 1z tracer of the 20x110 Hispano.
I notice the continual 'crimp' of the case to projectile,is this the norm for Belgian manufactured Oerlikon or has it been 're crimped'?

PS just had a close up view of this projectile and it looks like it has a 'punch' locked fuze? if so this would be a SAP (semi armour piercing)

That is the SAPI, the crimp seems normal for FN production, the one here juts got pulled or messed with so the neck went trumpet.
