Some asshole didn't let the paint fully cure before putting the plate on, and when someone took it off it peeled the paint.
Well, the screw slots aren't all vertical, like they should be. Any man should know that, Broom be damned.
Fuck that noise. 1950's steel boxes don't give you much latitude in getting devices to sit square and flush.
When you've got 1/8" on either side of the device and boxes nailed up in a manner other than "straight" and "plumb" and "flush", ehh, nope. Remember a 5-gang switch box I had to device on a job once. Stud twisted and warped, and the drywallers didn't try to take the bow out of it before nailing the rock up, the box was an inch out of level across the length of it. I've got a picture of it somewhere, it was hilarious when the builder tried blaming it on us.
