Vintage 8mm Film Work Safety Die Design, Cutting Bending Teamwork 3 reels

Description

I’m assuming all 3 reels are 8mm, but they could be Super 8- I cant tell the difference.
3 vintage film canisters with film reels:
“Cutting, Bending and Teamwork”
“Safety Considerations For Die Design”
“Equipment”
These are all from Rockford Safety Systems- I believe they are or were some kind of manufacturing company and these are some of their safety films. One reel has a note that it will not track the sprocket holes.
I am not able to view these films, so I don’t know anything about content or quality. Plenty of scratches and scuffs on canisters.
Please see pics.
