History:

Aetna Machine & Mfg. Co., manufactured a line of push buttons, switches and receptacle plates for electrical mains house wiring.  They were in business as early as 1906 under the name of Aetna Mfg. & Plating Co. with a factory employing 16 men located at 170 S. Clinton St. Chicago.  In July 1918 they moved their office from 322 West Kinzie St., to 625 West Jackson Blvd., Chciago.  In the 1922 Chicago Business Directory they were listed as machinists.

In addition to house wiring plates and switches, they also made the "Liberty Bell" automobile warning signal and the "Campfire Pal" camp stove intended for automobile travel.
The only radio product I'm aware of is the Aetna Tube Re-Activator which they advertised in 1926 and 1927 shown rejuvenating 01A tubes. 

This manufacturer was suggested by Matt Endicott.
