Grainy film with wide exposure latitude
I recently shot a partial roll of a mystery film someone on another forum sent to me. The canister says "GAF Recording Film Type 2005", the base is purple, and the rebate says "GAF SAFETY" and "2005".
Someone with an old imaging handbook found that it was designed to take photographs of hydrogen bubble chambers, CRT readouts, and other scientific equipment; its original speed was 100-160 in the 1970s. Manufacturer development information was nowhere to be found, so I stand developed it in 1:100 Rodinal for one hour.
As an aside, I have been searching for a certain low-contrast, high-grain aesthetic for ages, and I finally nailed it (by accident) by metering a 120 roll of Fuji Acros wrong:

Anyway, the results from this GAF film turned out to be exactly the kind of aesthetic I have been searching for, except reproducible. I may have underexposed this roll, so I'm going to try shooting the next one at 80 ASA. Here are selected results:

My question: is there any film and developer combination that's currently in production which will yield similar, reproducible results? I have five rolls of this GAF film left, and the person who sent it to me has forty, and is planning to shoot them himself. Ideally, I would like to produce photos like this forever, and I'm hoping it's possible. Bonus points if it's available in 120, so I can take advantage of my Pentax 67.
What EI and developer for the Acros?
Grainy film with wide exposure latitude
I shoot a LOT of GAF 70mm aerial film, (shot at EI 200) I find it high contrast because its an aerial film.

I've found it develops great in Ifsol 3 at 4 or 4.5 minutes. The short dev helps keep down the base fog, and gives nice tones but as I said its high contrast being an aerial film.
But it's certainly GAF from... 1967 I believe. And I've found it's a really nice film. Funny anyone who "remembers" it says it wasn't a good film, but I find it a really nice film, so, maybe it's gotten better with age

EI 100 in Ilford machine developer (I didn't have access to a darkroom at the time I took those photos, so I sent my roll to the local photo lab). I messed up the exposure by metering on the sand on the beach, though I may have used an exposure one stop below what the meter indicated. I don't remember

I dont know anything about it , but i love the first shot.
Yeah, something element doesn't seem quite right. I don't know what Ilford developer, machine or not, would make Acros look like that. I wish I knew, because that is an interesting look, and I prefer the Acros image to how the others shot on old GAF film look. If you can find a way to repeat your "success" with Acros, I don't think you need to look much further.
And the rest of us would like to know what the Ilford machine or its developer did to that Acros!
Ilford Delta 3200, as mentioned above, has a wide latitude and can be low contrast, and can be grainy, depending on how you expose and process it. Same with (now discontinued) Kodak TMZ. The more you underexpose either film and how you develop them will determine your results.
The Acros, as I said, is grainy because it was exposed wrong.
Your (under)exposure error of a couple stops would not cause any such graininess on Acros, it'd just cause a little shadow loss. It might be down to the developer maybe if you used print chemistry? What you've shown isn't anything like normal Acros behaviour or graininess; it should produce a grain-free print at 16x20 or so from that size negative.
My guess is that it's a grain-aliasing scan problem magnified by the huge contrast boost given to recover the probably-quite-thin negative.
