Here’s the NOS hinge that’s now partnered up with that in post #2. This hinge was tight and didn’t require a rebuild. Note the thick layer of dust from years and years in storage. It’s old NOS imo and the rivets are more deeply furrowed than those in #2.

I'll have to see if I have a picture, but I believe my original rivets were exactly what's in that picture P. That hinge looks sharp. Phosphate is the way to go, I don't know a place. I'll pic of my replacement rivets and new finish, just dropped them off to the Ceracote guy today. I believe the replacement rivets are very similar or same your first picture.
The one NOS I've seen had small rivet ends and looked too perfect if you get my meaning. Looked like say a coin battery with a plus sign.
Washed the oil off my blasted hinges, at least they move now (yikes). With oil smooth as silk. The guy who rebuilt them recommends seafoam deep. One minute you're spraying the next can't even hold onto the can
If you think of it, I'm curious what the front of the front cross support looks like on a new-ish OEM hinge. There's a bow to it. Or at least better be, all four my hinges have it
Perhaps the rear too, but the front seems most vulnerable to stress.
