Is there a big difference between the 80 & 85 and the 'C' versions of these filters? Will they be a just little cooler or warmer or way the hell off? I don't have much experience with them except for the little "daylight" switches on my Elmo 1012 and Canon 514.

I bought a Bolex DS8. They don't have filter slots like the H16's so I bought a few NOS Kodak series 5 filters (for those dinky switars) but all I could find so far are the 'C' versions. At this point in my expensive hobby I'm more concerned with matching my footage than having an absolute color temp.

That being said I'd like the color of my matching footage not to look too ill. So far I've only shot B&W with it.

Thank you.

Well, the "C" versions are not full corrections but if you're shooting color neg, it will probably be close enough that you could correct further in post without any problems.

The 85B filter corrects 5500K (daylight) to 3200K (tungsten).
The 85C filter corrects 5500K to 3800K.

The 80A filter corrects 3200K to 5500K.
The 80C filter corrects 3800K to 5500K.

But if you are shooting color reversal film, it becomes more important to get closer to the final color you want, although it only has to be exact if you are planning on direct projection of the original. For telecine work, you can compensate if the color is slightly too cool or warm, but don't push your luck.
