Author Bob Jeschonek at http://www.robertjeschonek.com/ wanted to point out long before "The Johnstowner" there was "Johnstown Man" back in the good 'ole Flood City Comics days. Although, I've heard of Flood City Comics, this was the first I had heard of him. Check out out the eerie similarities! Fortunately you can see what a difference a blast furnace in the chest and being part iron and steel can make.....not being sued for gimmick infringement!
You can check out Bob's Johnstown Man adventures in the Archive section on his site. Enjoy!
