Can you identify film, ISO and dev process?

Whatever it is, it's a high acutance combination (except the interior door shot) and it doesn't look like push development, as the highlights aren't severe. and the microcontrast isn't high. It may be more "printing down" than underexposure, as the shadows have detail. The lifted black may be "post scan."

The grain is similar to 400 speed 35mm film in Rodinal. I'm betting on Tri-X or HP5. Looks like a 35mm or 50mm lens, and since the last shot has stuff just at the borders which he seemed to be trying to exclude, it's probably an SLR with viewfinder coverage that doesn't quite reach 100%. Based on the angles in the pictures, and the softness of the indoor shot, he was most likely working without a tripod. These are all just guesses.

I understand what the OP is looking for, a way to achieve an atmosphere. And he hopes to find it through a certain technical approach.
But these techniques are in a certain cense 'old', perhaps no more available, and even more the result of very personal way of combining, practicing and seeing.

I was looking for some kind of 'dark' atmosphere for visualising a very specific subject too.
I found it not in the use of a particular film nor developer, even not in the printing, but in the use of a contrast filter on the camera: a Hoya SR-66 (and Hp5+ at box speed in ADOX XT-3 1+1 and low angle January sun).
I don't know if David Lynch used a red filter, nor do I know what film-developer-printing technique, but I would suggest to give the use of a contrast filter a try.

Here is an example of what I am trying to say.
But please bear in mind that what you see here are two bad digital reproductions of FB prints and inconversant Photoshop fiddling, and above that I was somewhat to enthusiast in applying some vertical mouvement...
