Description
The Nagra III recorder,
first developed in 1958, was made in relatively small quantities by Kudelski
of Paudex-Lausanne, Switzerland. It was a fine example of Swiss craftsmanship:
the case being fabricated in heavy gauge aluminium and every knob, roller
and control had an indefinable feel of perfect engineering.
