Op1 original UK repair

Hey! I have an unresponsive #3 key. I’ve tried removing and cleaning it, no joy. Looks like both TE and ifixit have been out of replacement key beds for a while, so wondering if there’s anyone in the UK who might be able to help me out with this? Seems a shame to just have the synth sat being unused, and as tempting it is to upgrade to a field, I’m nervous about being stuck in a similar situation again in a couple years time with that too.
