If it's just the basics you are after, then this one is the the Oerlikon 20 x 128 developed in the 1950s for the KAA, KAB and KAC automatic cannon. It was (and still is, although its now all one company) a close rival for the Hispano 20 x 139 for the HS 820 etc.
What does the 11 on the headstamp stand for?
