Hi Phil! In The Ring, July, 1978, is reported;
Montecchio-Dante Cane won the heavyweight championship of Italy, halting Renzo Trevisan, three.
I have never seen or heard about a Renzo Trevisan, boxing on that level.
Have you?
I questioned this a long long time ago when I came across it. Not sure who came back to me - may have been Barry - but apparently it is incorrect............so where did it come from then???
