I've been informed from Tania, that George Lovely, Jr., may buy the dies/casts/molds from Steve Tomberlin so we may not have seen the last of Air-Way.
If in fact George uses any of those dies, the name would be something else. He is the current owner of the Black Knight vacuums which are very similar to the Sani-Clean/New Century.
That company also makes the filtrete bags which fit all the Air-Way models from the 55 to the last machine including the Sani-Clean and the New Century models.
