This is where the bastard bar was
I could fill the page with numerous pic's of close ups of the bar's on both sides.
Frankly - no need. There is literally nothing to see. It's old, it's not polished (it was never meant to be seen), there is no sign of any deterioration what so ever.
I completed training as a metals processing specialist for the USAF in 1980. I can weld, forge,treat, bend and cut etc pretty much anything with the caveat that this was 30 years ago. That training including NDI (non-destructive inspection).
This bar is fine for another 30 years, if it was in one piece.
