The Nagra III was released in 1957 and was a technological breakthrough! The fact that many Nagra IIIs are still working today speaks for itself. The Nagra III is in some respects the father of all other Nagras as it bears the iconic large modulometer and rotary selector. The first Nagra usable for film work, appearing in 1958. This was a monaural recorder, with the "NP" denoting the Neopilot sync.
