I asked Warfield in September 2000 about this typewritten paper and he gives only a guess that it was about 1982. He is not positive at all about the date. It was written before he came to George Mason University and after he left Battelle, we think. In the 2 page manuscript, the first page is a nicely typed and centered title page. The second page is a list titled: "Transparencies needed from two recent papers." If we knew which recent papers he was talking about, we would be closer to a date. A list of15 transparencies is given.
