C-41 is easy. You need a water bath to keep everything the right temperature, and a C-41 kit -- modern ones have two baths plus a final rinse, though a stop bath isn't a bad thing to add. You may still want to get some formaldehyde -- the stabilizer you make with that plus C-41 final rinse will keep well and can be used until long after the C-41 chemicals are exhausted. Do use that only with strong ventilation; formaldehyde is bad for humans.

Okay, thanks! Ill have to have a barely warm water bath, and I already have stop bath for B&W developing. I'll have to try and find the recipe for the formaldehyde stabilizer, and try not to die.

For genuine C-41 on C-41 film, the bath temperature is 100F -- and you'll want a thermometer, because it needs to be right on temp to get accurate color.

C-41 used formaldehyde stabilizer into the mid-1990s, so that'll give you another search term to use.

Would this be of any help?

I also found this which is related to the old Agfa CNS negative process but I wonder would to also do for the old Agfa AP41 process (the Agfa transparency process prior to changing to E6 in the early 1980s)

I know Agfa made private label film in both colour negative and transparency before and after they changed to the Kodak processes.

I am reasonably sure that all Focal brand colour film was sourced from 3M-Ferrannia.

e4 was a lower temperature than E6 so E4 film needs lower temperatures.

AGFA CNS was a unique Agfa process. when I was selling film, the place I worked at used ETCO photo in Montreal, and they were one of the few labs that could do CNS. Probably as part of their contract they even printed it on Agfa Paper.

I'll check out that first link. I dunno about Agfa CNS, I was pretty sure this is Ferrania film.

I've got photos of the film and camera:

Great photos of the film and the camera.

Made in the USA (and the expiry date 1974 & 64ASA) would suggest the film could be one of the following, according to my BPJ 1974 annual.

3M colour slide film.
Gaf (Ansco) 64 colour slide film.
Ektachrome 64 colour slide film.
Kodachrome 64 (highly unlikely)

From looking at the packing carton and the instructions could it be Ektachrome? The slide tray looks very much like a Kodak carousel, it has its distinctive shape.
Speculation can be fun

I know that Ferrania/3M made film for Focal, so it's probably that.
Ektachrome would be really cool tho.

Problem solved! "Price includes developing." Just take the exposed film to any K-Mart and they'll process it and return your mounted slides.

Oh wow, I can't believe I didn't see that before! I'll have to take it to the abandoned K-Mart in my town, and ask there~ Thanks! : )
