For anyone who has tried restoring a ZX Spectrum dk'tronics keyboard, you may find that parts of the PCB track fall off due to corrosion. While I was restoring mine, I realised that the PCB was beyond repair after removing the switches for internal cleaning.
I have scanned and re-manufactured the PCB and have a few for sale on eBay:

These are only for sale in the UK, but should there be any interest, I'll open up the listing for sale overseas.
The dk'tronics keyboard wasn't the best aftermarket keyboard for the ZX Spectrum, so I'm not expecting an orderly queue, and the amount I'm charging for the PCBs is basically to cover my re-manufacture costs.
In the attached image, the new PCB is on the left, the original corroded PCB on the right.
