Uhm... This should contain V4W SDK:

But it's likely that it won't contain DCI stuff (anyway, I would still check) as it's from 1996. Maybe an earlier version of MSDN cds from 1994?
I found this one, but it has a bunch of (7z compressed) iso files:

I would check WIN16 and WIN32SDK discs. I guess ADD_16BIT and ADD_32BIT are likely to contain addons for 16-bit and 32-bit SDKs. Might be worth checking too. The rest CDS are likely related to Windows NT 3.5 (or its beta).
There are docs for VFW 1.1e DK here, but no downloads:

As Jumper said this might not contain DCI stuff. Although, looking into it, they only removed dcivesa (or similar - which is a generic DCI driver) from redistributable. Might be possible there are other DCI drivers in it. Or not. Should be checked. Same for DK.
