It's long, about 30 minutes, but I found it interesting, even if dated. Kind of took me back to grade school the way the film plays out. All those Bell Labs movies too.
I don't think they'd show some of the content today, even in modern form. The carcass handling and skinning systems were interesting to me but I can see where it would offend modern sensibilities pulling the beef skin off the carcass and salting it for shipment to the tanners. They don't want to know that their food was once a farmyard favorite playtoy (If I can misquote Howard Jones)
Other highlights for me were the elegance of the ham cutters removing the leg from the carcass. They made it look effortless. The bacon slicer was impressive too.
