In that era, Rohde & Schwarz often sourced pushbuttons from Preh (https://www.prehkeytec.de/, they no longer make this kind of buttons) or Schadow (today part of Littelfuse/C&K Switches, https://www.ckswitches.com/).

The button caps on the SMS look similar to these, but I'm not sure: https://www.ebay.co.uk/itm/115873394817.

Edit: The Schadow "Digitast" series pushbutton switches are still available. Maybe the ones with wide button caps match the SMS.

Edit 2: Some more ebay finds:

These are Shadow switches indeed. You can gently pry off the keycaps and transplant these to new switches.
