Check out the bottom axle in this pic. If I'm not mistaken, it's one of those 1935 Worlds Fair jobs where they would twist them up and remount them to show how they still worked just fine. I don't worry about Henry steel flexing, but I'd be worried about that axle. When it comes to concerns over important components that could kill you if it failed, why spend time and money to confirm crap isn't crap when you can swap it out and sleep at night? Didn't that fireman fellah that almost died here in Burbank last year have his Superbell crack in half in the freeway?
