Bright Star Battery Co.
Bright Star Battery Co., 310 Hudson Street, New York, New York, USA
Last seen: no advertising found
Bright Star Battery Company appears in newspapers starting in 1921, but it would be some years before venturing into branded radio tubes. For many battery companies, this made perfect sense. Bright Star was advertising their 22v batteries
along-side tube sockets and grid-leaks, and their brand was successful.
They appear to have a Chicago battery plant open by 1924, at 562 West Monroe Street, Chicago, IL, USA
If it werent for an eBay photo, honestly I would never guess Bright Star made a 201A.
