I first watched this video when it was posted to Periscope's youtube channel 3 years ago. Since then, I've wondered 1) why this video is not included in ATTTechChannel's AT&T Archives[0]? 2) why it's in the hands of a private stock footage company? Periscope says they saved many of the 16mm military reels in their collection from the landfill/incinerator in the 40s-70s[1], but why would Bell have tossed this? Seems bizarre.
