BLD522,
Mike stewart has released several knives in 50100B (0170-6C) (some appear to be made from old CS recon-scout and trailmaster blanks). The 9" bowies are up for sale now. I think he has had others. I seem to remember he said in a thread that he and Jerry split abunch of it. There is no other source for 50100B at this time.
