Our friend Sean Charlesworth stops by the office for this week's Show and Tell to share another cool piece of technology history from his personal collection: a Nagra SN portable audio recorder. This series of miniaturized reel-to-reel recorders were built in the 1970s and used during the Cold War as covert spy recorders by the CIA.
