What a cool machine! Congrats mate.
When is it from and what was it mainly used for when it came out?
Some of the Nagra's been used for military purposes as far as I know.
Not my recorder my friend,...just posted here for some "eye candy".
This is all I can find on the Nagra T:
The Nagra T-Audio
First introduced in 1981, the T-Audio is a two track analogue transportable recorder designed for studio recording. It is designed to be trolley-mounted. With programmable combinations of up to 4 different tape speeds / EQ settings it can be entirely customized to different tape formulations, transport speeds and equalization parameters. Using the Twin-capstan tape transport system developed for the TI it handles master tapes with a delicacy not before seen in a studio recorder.
Initially it was a stereo recorder / player aimed at the disk mastering industry. A monophonic model was also developed. A twin track version with an independent erase head for each track, and was aimed at the radio broadcast industry. In 1984 a full time coded SMPTE / EBU version was introduced and became the industry standard for audio transfers for film applications around the world. The different models, although mechinically very similar, were easily identifiable by the removable control panel or "keyboard" mounted on the front. (The machine in the above picture is equipped with the TACA-TC keyboard). The T-Audio manages rells up to 10.5 inches in diameter and can be equipped with a magnitude of different options and accessories for many different applications.
Different models were:
NTA-2S - Stereo Model
NTA-2M - Monophonic version
NTA-2B - Broadcast Model
NTA-2TC - SMPTE Time code model
NTA-3TCN - Time code without internal chase synchronizer
NTS-3TCS - Time code with internal chase synchronizer
NTA-3TCR - Time code with internal chase synchronizer and RS-422 serial control
The NTA3-TCR was equipped with the TACA-TC-2 keyboard which incorporated many new features including a full time code calculator. The keyboard is connected to the T-Audio transport with a serial interface allowing much more information to be displayed from the time code circuit on the main display. The mechanics of all T-Audio machines are principally the same.
