Don’t get it, if all the negatives are black and white film, C41 processing isn’t appropriate because it’s for color negative film. Not to say someone came up with some not-what-mom-intended use-case, but the directions don’t line up with that.
Never mind, you have it all in the post. The BW400CN is color-negative film, the Ilfosol 3 is B&W. Corresponding processes for corresponding film types.
Two different B&W films… Ilford FP2 Super 400 and Kodak BW400CN.
Both are labeled as C41 process, but the Ilford has verified Ilfosol 3 development times (as per Massive Dev Chart, an online resource stating known development processes) even though its a C41 development film
Yeow, out of my league now, had never come across such films.
Did run across this: https://mrleica.com/kodak-bw400cn-film-review/
I guess I’d still try to go with the instructions on the little piece of paper packed with the film.
Hah…I never had that little piece of paper 
But, I think I’m going to give it a shot. I don’t remember what’s on these rolls so I don’t think I’ve much to lose if I don’t hit the target with all of them.
I’ll chalk it up to a learning experience.
Thanks for your help though…I’ll keep this updated through the week. Ultimately, these negs will get scanned and then processed in darktable.
Not sure I was much help… 
One of these days I’m gonna get up off my dead a$$ and expose a sheet or two in the old view camera. Will study your darkroom journey closely…
It may turn in to a journey. The local camera shop owner is heading j km to retirement and offered me a respectable darkroom setup for$250 cdn.
I must… Show… Restraint…
For the C41 black and white you’ll get the best results from sending it to a lab. They expect the full develop, bleach, fix process so you usually end up with a lot more base density than your trad black and white films. I’d be sending them off myself.
C41 B&W came around because when sending to a lab you pay less for C41 development than for black and white as each black and white film stock requires different times while C41 is a fixed process. I know my local lab sends their B&W home with a technician that does it in their kitchen sink, just as you would at home. The volume isn’t there to make it cost effective any more.
Ok, gave two rolls a shot… Not the c41, just two rolls of standard B&W film.
They turned out decent. Quite dirty and scratched but I am still pretty excited about it. I edited one jpeg file for kicks, and in the morning on going to try to scan the last 30ish frames that I’ve developed.
Congrats! That’s awesome. Looking forward to seeing more. Nothing feels as good as developing your own film.
That misty shot is really cool.
Re dust on the film, I have found it helps a lot to rinse in filtered or distilled water, then handle as little as possible when hanging to dry, then immediately before scanning (or even every few frames depending on scanning set up) gently wipe with a lens cloth to remove dust.
Oh yeah, absolutely use distilled water with photo-flo (or any other surfactant, like dishwasher rinse aid) for your final wash. Another tip if you have bad dust where you are is to run a hot shower and steam up your bathroom then hang your film there to dry. Takes all the dust out of air really well.
Also, never use a film squeegee, you’ll just scratch your film and it doesn’t speed up drying that much at all.
Performed a few more scans this morning… I’m looking forward to processing the saved tif files in darktable when I get home this weekend.
These are just a few quick Snapseed edits from the few frames that turned out ok.
Really love the first 3 and looking forward to the final edits
Oh hell, I’m going to have to drag that old camera out now, put it on a tripod and stare at it for a bit… 
I really like #26. The way the light sculpts the “cliff” almost looks like flames behind, what I think is, a burn scar from forest fire.
