Just gathering information....February 27 2007 at 8:11 PM
Response to Thanks!
I am gathering the remaining information I have. Unfortunately, there are more holes than gruyere cheese!! In the meantime, I recommend you to go to google videos, then search for "the invention of ethiopia", then look for the 9 minutes video, and pay attention to the the sequence when Haile Selassie aims/fires an AA gun: believe it or not it is an Oerlikon Model S!! (sometimes refered to as M1928 or M1931). I had no previous reference of this modern gun in the ethiopian army´s depot - keep in mind the the other model was the older SEMAG mod. L (or Oerlikon M23). I do not know when this gun got there, and how many were purchased.
More traces of information to follow - soon, I hope.
