Again have a question about a, probably british wrestler taking part of the great vienna tournament at the "Heumarkt". From June 7th to 14th 72, a Yukon was here to wrestle for a few bouts. I found a Billy Yukon in the A-Z. Could it be him? As you can see at the paper clip other participants are Shirley Crabtree (here as John Crabstree), Jack Rowlands, Don Vines and El Cameron. Maybe this helps a little bit.
Thank you
The tournaments in Vienna continued every summer well into the 1990s long after the end of the ITV broadcasts
