Ok MDWC and McGrain, here is the mail a fine upstanding gentleman called Steve sent me. Dinner might even have close to immediate access
Hi John
There are a few sources for this. A couple that spring to mind are the U.K's 'Boxing News' publication and Dr. Jan Skotnicki's book 'History Of The Heavyweight Title'. I've just looked at the book again and it confirms the data that I posted on the BoxRec website.
Hope that helps
