Fellow Redditor catsontuesday found a gorgeous Siemens keyboard with missing keys, but the challenge didn't frighten him.
The Siemens Unity 2 is allegedly a rare GMK board with GMK caps and MX Black switches. Full NKRO (diodes on every switch) and PS2/USB connectors.
It has a rubber sheet over the switches that make the keys feel HIDEOUSLY spongy but very quiet as well – catsontuesday.
This is a device for an audiometry machine (the metal knobs are audio seekers to be used in the Siemens software) so proper soundproofing makes sense.
More pictures about a similar model with photos of the rubber membrane in this DT thread.
