Cubase plastic overlay for Alesis Master Control

This is a definite shot in the dark, but I recently bought a used Alesis Master Control Unit and it did not have the plastic overlays for Cubase that came with the new units. There are two of them. What I’m asking is is there anyone out there who might have such a thing around that they would give me or sell to me. It would be a massive help to have such a routing overlay. Maybe even a photograph of one would work for me. I could make my own. Any help as to where I might find such a thing would also be most helpful. Alesis is no assistance, they’ve washed there hands of this device long ago.
