I suspect your thought on simply folding the sheet metal one way or the other is correct. I notice that the KO slug is on the inside on this model, if you have an equivalent fixture in white, it would be interesting to see if the slug is on the outside. Everything about this fixture seems to indicate it should have a grounded plug. Metal enclosure, and no double insulation between the live conductors and that metal enclosure. What I don’t know is when that standard went into effect. Electrical safety has come a long way.
Typical low power factor ballast, likely from the 1980s or early 1990s. Later magnetic ballasts including those made until the phase out of magnetic fluorescent ballasts in around 2010 had a capacitor to raise the power factor to 0.90 give or take a few. All new metal halide and high pressure sodium magnetic ballasts are high power factor as well.
I love noisy ballasts, nice to have a vintage preheat light fixture buzzing away, nice ambiance inside the shed or house!

I love the sounds they make
it looks like the ballast isn't installed properly, maybe that's why it's making so much noise. see 3:15

That's what we call buzzmatic. Although if you put a magnetically palaced freestnt light on a modified sign wave inverter, it is pretty buzzy as well.

Choke Ballasts don't really have a defined power factor on the lamps all they are is a transformer
