As for the top unit:
The first stereo analog recorder in Nagra’s range. An icon among sound recordists, film and record producers. The unique texture of a Nagra IV-S is still unparalleled and some demanding customers still use it today.

Note: I know absolutely zippo about this brand or their products, but wanted to add a whiff of context for those curious...
When electronics have that rugged exterior look is when you know it has the potential to be really high quality
That 'rack' look... plug in, pull out... arrange to your technical needs!
that 2nd picture with the custom bag to hold the device, the custom machined face plate
immediately signals that the creators are doing everything they can to make a quality device
For sure. I have no idea how Schweiz engineering and product comes close to Deutsch engineering, but it seems to me that... there may be some connection?
