Hi Danny,

The difference between the models mentioned are centralized to the main PCB, but things like keys, button switches, etc. are interchangeable.

BTW, the keybed is a FATAR action and it shouldn't be difficult for a keyboard repair facility to order the appropriate keys.

Also I know there is a product that can polish out fine scratches on plastic. I'll try to find the name of the product and report back, or you could do a search and probably come up with something.

Best Regards,

Dave
