Carrier armour manufacturer?

That surprises me too. I have to wonder why they would not have punched them while still somewhat mild, then go through the hardening and straighteneing process. One would think the punching process woudl add stress to the plate.

As I mentioned earlier, on the hull I just sandblasted a couple weeks ago, it could be seen where the holes were cleaned up afterwards for things like the smoke discharger and the antenna mounts, but not for the rivet holes. Perhaps those were cleaned enough when they coutnersunk them.
