Old School Wrestling was an independent promotion purchased by the NAFW to serve as a "minor league" organization like IVW. After a short but sweet run, OSW was annexed into the NAFW. Its last champion would go on to carry the title throughout his time in NAFW, but it was never officially recognized as an NAFW title. However, it was put on the line in a unification match of sorts for the X-Treme Championship, which Krychek won.
