Well, from the scant information, the GAF film may not be for USAF use. That is a guesstimate for now.
Our cannisters and rolls fit our cameras as easily as any other camera. I have some 5" and 9" rolls here AAMOF and they look just like film rolls.

I have quite a bit of their Hyfinol developer and Hyfinol Replenisher. Most is in Ansco cans, but I have a few branded GAF. It's a nice developer and pretty unique, but results not wildly different from D-76. I read some discussion about Hyfinol by Patrick Gainer a while back. He liked the stuff and tried to reverse engineer it (fairly successfully from the sound of it). I also have a bit of GAF Permadol; I believe that was their standard tank developer.
I can see how it would be interesting to find the manufacturer's information, but I don't think it would really be helpful. I have directions for the Kodak aerial films (which I shoot in Cirkut Cameras) and the directions for aerial use are nothing like what is needed for pictorial use. You just have to test and find the best EI and developing time for your use, as with any other film. You've got a good starting point, which is the hardest part. For myself, I'd want about a stop more exposure than the negatives you showed earlier. At that point you might, or might not, end up wanting a somewhat shorter developing time too (maybe 20 percent).
BTW, I shot some of that same GAF film in 9.5 inch when I first started with the Cirkut Camera back in the early 80's. I took one of the nicest black and white shots I ever got with the Cirkut on that film (already well out of date then). I imagine I developed it in D76, but don't really remember. It was very nice film that I didn't fully appreciate until it was too late to find more.
What's "our canisters" mean? Do you work someplace I'm supposed to be aware of? Do you mean 5" and 9" tall roll film? Wow what is that even used in? I thought that big you had to use sheets because of needing a flat/even plane over such a large surface area?

Matt;
That shot is in my gallery!

I was in the USAF and worked at EK, so I have worked on both ends of the supply chain. Aerial film used by the USAF was procured from either EK or Dupont and came in 5" and 9" rolls. These rolls were exactly like 120 rolls but bigger and the film length was about 90 feet. They were used in aerial cameras, and I have posted a picture of an RF101C that I took while the plane was being serviced. The open bays shows 2 or 3 cameras. They used 36" lenses or about 900 mm. The cameras produced overlapping frames that were read on a special device that produced 3D images.
BTW, your hanging film shows no perfs, but the closeup sample has perfs. Whats up?

Alright, I have checked the USAF Handbook for Photo Lab Processing (AFM-96-11. In it, it lists films used by the Air Force for all purposes and for aerial use only Kodak and Dupont are listed. GAF is listed for small camera and sheet films. No joy here! Sorry.
Also, it gives the standard developers to be used. All films must fit a narrow gate for time and temperature in these developers.
All must be able to use darkroom or field equipment.

Well, it looks as if it is a NATO number.
Yes Stone, subscribe.

What I found most annoying and strange is they come in canisters of 15 feet each like standard Kodak 70mm except NOT in load able canisters, but just on spools, and the spools do NOT fit in 70mm canisters so I STILL have to re-spool them as if they were on 100 feet spools, why didn't they at least fit inside standard canisters... Ugh, I'm sure they are some proprietary GAF product but still silly, at least the bigger spools prevented heavy curling...
