Some of what you say is right, but don't count on all of it. I used to work for GM just a few short years ago, when OSHA was in full swing. There were plenty of machines, particularly presses, that had no guards and no 2 hand switches.
I think the crankshafts and mechanisms would be shielded, but not the contact areas for the parts.
Besides, there were NO safety shields in place for the most dangerous things in the plant, humans!

Yaagh - exposed punches with no guard cages, crankshafts with no guards - oh yeah, those clips are OLD - OSHA would be screaming. Things like that switch assemply could be open air, BUT they would have to have "2 hand" deadman switches
