Vintage Majestic Super Power Tube Model AQ Gas Rectifier 1920s Engraved Antique

From my research, I believe this is a cold-cathode gas rectifier used to convert AC into DC in vintage Majestic radio power supplies and battery eliminators, circa 1920s.

Tube is in used untested condition. Please review all photos carefully for cosmetic condition.
