Until late 1924, there are few specific mentions of 'Air-Tron' brand tubes, but we can trace backwards the street addresses used to link earlier advertising for the 'manufacturer'. All indications from evidence suggest that H&H Radio Company was not actually making 'Air-Tron' tubes, as much as they were rebranding repaired tubes, relabelled 'Air-Tron'

September through December of 1924 saw H&H radio company pushing a branded tube, the 'Air-Tron'. Advertising has been found in Radio World, Radio News, and Popular Radio. The above two ads are from Radio Digest, 1923.

Air-Tron's ad in Radio World, 20-Sep-1924, suggests they were selling a full range of tubes, as they could if they were rebranding repairs!
