I had that one ID'd a couple years ago, but I can't remember what it was. It is not Marvellous Cain. The second or third bootleg of those records (FB1, FB2, FB3, etc) actually does have Guntalk by Marvellous Cain on it. I think someone just screwed up when they were writing on these records, unless it was etched in. My copy has no writing on it, but I've seen others that do. I just remember the word gun being part of the artist's (not DJ Gunshot, though) name or the song title, if that's any help.
