I was just reading about Finnish Wrestler, Waino Ketonen (who apparently had a hand in training Billy Riley), and it appears that Ketonen won a Lonsdale belt by beating one of the Carrol's or maybe Tom Rose. He could have also borrowed it from Peter Gotz, who appears to be in the USA at the same time as Ketonen. He claimed that the Lonsdale Belt was the legitimate World Middleweight Championship belt.
