I just randomly found this online while searching for something else, and I thought I'd share it here.
Apparently, Jack Dale's travels saw him go all the way to Turkey in 1952. Here's a poster for a series of pro wrestling shows in Istanbul, Turkey, in December 1952. He's billed as the English champion. The five shows were to be held at the Istanbul Sports and Exhibition Hall, which had a seating capacity of 7,000.
Actually, the one next to Les Thornton looks a bit like Steve Clements?
