I've seen those before. The bottom one is listed as being one of his fights with Fred Cochrane, but it looks to be the same as the one above it. Angott and Cochrane looked and fought somewhat the same way, so it's hard to tell which one he's fighting in those clips (I had always understood it to be Angott).
I had run across these when I was reading a Wiki article about Angott. I had never seen Zivic footage. His style kinda reminds me of Sharkey.
