adb extended keyboard II keys?

[refinery]

Does anyone know if it's possible to obtain replacement keys for old keyboards anymore?
After my recent move, I discovered one key had been damaged on my extended adb II. It's done, there's no way to save that key. And it's an important one... The period key.
Profound sadness ensued.  This thing isn't even yellowed hardly. Hopefully someone out there knows where to find them or somebody's got a broken one they can get it off of.

Your best bet would be to find another keyboard on eBay for spares/repairs
