Unknown 20mm shells

Can anyone tell me what these 20mm HE-shells are? They most likely are post WW2. No markings and fuzes missing. Fuze threads are very large and very fine. Note steel driving bands.

These shells look like they are for the 20 x 128 for the Oerlikon KAA cannon. I believe it was developed in the 1950s and may welll still be in use today. Other than that I can't help you.
Thanks for info, this could be it - we had a few guns in test use in Finland in 1960's.
Here a picture of 2 other unidentified 20mm shells - any ideas?

The top one looks like an APHCBC (Armour Piercing Hard Core Ballistic Capped) for something. The driving band looks similar to the Oerlikon KAA, but is copper.Other than that, I can't help you. What is the bottom one made of? It looks like solid brass or copper.
