IDK. I didn't enlarge the thumb lol!. Yes, probably 8", maybe the plastic envelope was around 9" ... some of the nuts in the lab would cut 2 sides of the 9" envelopes and wore them as floppy hats when goofing off.
The 5 1/4 was the new and improved version. Then the more durable 3 1/2 floppy (in a thin hard plastic case and sliding window) came along (used HP controllers, Apple Lisa, Apple Mac, ...) 1983-1984. Portable data storage was a fast moving target back then, around the same time of VHS vs Betamax wars.
None of my CP/M machines are new enough to use anything other that 5 1/4"
I just searched for MCT-2000, a PC based 64 pin digital test system we embraced just prior to the production of the FACT line (CMOS) digital devices at Fairchild ... I couldn't find any pictures of it. We ended up shipping all of them to Asia in the late 1990s. They started out with 8" floppies. These floppies were so problematic that we networked the testers to the mainfram by mid 1980s.

That's not surprising, a lot of that early computing technology that wasn't consumer based is lost to time. I used some giant machines that were Intel branded, that's the only place I've ever seen those devices. Ma Bell made a lot of her own internal use only computing equipment, and all of that stuff was just junked when no longer useful.
