Found old videos of possibly Quake/Wolfenstein models?

Hey, guys! I just rediscovered a handful of small videos that I downloaded a LONG time ago that showcase various models for a, at the time, possible upcoming Wolfenstein or Quake game? (That's my best guess.) For the life of me, I can't remember when I actually downloaded them. I think it was in the late 90s, but the last modified date on the files is from 2003. (I think it was during a major system overhaul and any files I had backed up were just copied anew. ) ANYWAY, if someone could check them out and see if they could figure out what they were for it would be nice to clear up the mystery.

I uploaded them to my Dropbox here:
