Pet Rescue: Sorry, the only "spare" is my complete 610 which currently does not work but also is not in a state where I will begin to pull parts from it.
CBM 700 series keyboards have the same type of keys, in case you find a such one e.g. from Germany.
B-series keyboards crop up from time to time on evilbay, especially in Germany. I picked up a nice condition working one last year for around €15-20.
