This blogger could find virtually no information about McGinnis but he was important enough to have a photo on file in 1939 and be in the newsreel of a match (at link below) believed to have taken place circa 1939 in Los Angeles.
“For the first time online, here is Cowboy (Killer Krippler Karl) Davis vs Terry McGinnis from Los Angeles. The match is from the 16mm film titled Through the Ropes and was issued in 1940. Both Davis and McGinnis were mainstays in the Los Angeles territory for many years.” Excerpt from the youtube posting.
The video at the link shows the violence of the sport. Watch the 8 minute 41 second video to the end to see what happened after the winner was declared.
