Royce Union! - Joy and sadness...........

So I got an old folding bike - a Royce Union yesterday,,,,,,,,,,,,,I loved it.

All original, a little rusty, but workable I thought,,,,,,,,,,,,,,,
And then I tried to fold it. It didn't want to, so I threw on some PB blaster and tried to work it back and forth.............and then I did this:

The front part of the hinge is fine - the back part is twisted - I didn't realize I was that strong! Anyway by the time I realized I bent it the hinge was swinging fine.............Now it will fold but not reconnect - what now?
I don't know if I trust bending it back, it might be weak. UGH!!!!!!!!
