20 mm Oerlikon HZ Projectile Drawing (1936)


#1

I have found this nice color drawing of a 20 mm Oerlikon HZ projectile in the Argentine contract documentation:


#2

Hello Fede
When was that contract done?


#3

And:
Was this ammo for the Oerlikon 20mm L70 Modelo Argentino 1938? Which Oerlikon gun was this?


#4

Hello, the different documents of the contract were approved by the Argentine Comission between mid to late 1937. The guns were JLaS and PLaS models, both adopted as “Modelo 1938”.


#5

JLaS and PLaS sounds like mounting designations to me. I suspect it was the Oerlikon gun type S, chambered for 20x110RB, right?


#6

The gun alone was designated Oerlikon S, but JLaS and PLaS designates a complete gun in a mobile (tripod/wheeled) or fixed (pedestal) configuration and not just the mounting. You are right regarding its caliber.


#7

Thank you for clarifying that and for showing the colored drawing (I just know a b/w version until now).


#8

Some ammunition in this caliber made in and for Argentina during the 1970-80’s was even marked “Cñ ILAS L/70” or “Cñ 20/70 ILAS”, so here is not rare to hear collectors call this case type the “20 mm ILaS”.

Also, I forgot to mention that the first Argentine color code for this projectile was all red (except fuze).
