According to Wikipedia, Columbia Records’ manufacturing operations were based in Bridgeport CT starting sometime between 1912 and 1923 and continuing until 1964. I’ve been in Bridgeport for the better part of the past 13 years, constantly digging for audio-archival relics, and this small lot is the first batch of 1920s Columbia materials that I have ever come across. Columbia material holds extra interest for me as I spent roughly a decade working for Sony Music (modern parent of Columbia Records) at their Manhattan Headquarters.
The Bridgeport Columbia plant still stands, now condos; little other reminders are present of this important part of Bridgeport’s industrial history.
If you, or a family member, worked at the Bridgeport Columbia plant, please drop us a line. Chris@PreservationSound.com
