    Mystery piece

    This came in a lot darkroom items I recently purchased. I thought, at first, it might be part of the Patterson System 4 tank system, but it doesn't appear to be and the message, "Warning: Always keep CD wet while resurfacing" is anomalous. CD resurfacing?

    Note how the center is built to lock/trap a typical cd onto the surface. What you see is the drive gear.

    Thanks to both. Just couldn't understand why such a thing would be in with darkroom materials. Creeping digitization strikes again!
