Sutton notes in "Pseudonyms on American Records" that Kaufman's "...name was used in error for Arthur Fields on at least some pressings of Grey Gull 4122-B," but the 78 Online Discography lists a different matrix number (3027) for the Arthur Fields' b-side, so maybe some b-sides of this record just carry a different recording of the same song by Fields, and the disc shown has a Kaufman recording?
