Carbon Scroll / Volume wheel Part Number?

Since the Carbon is dead more or less... any chance of posting what the manufacturer and part number is of the scroll wheel encoder? I have 2 of these here with that problem. I was able to use the screen from another Carbon to fix one but can't find the part number listed anywhere on the encoder other than

JPN M(with a circle around it)
And on the other side is 40 and then III

For people searching, this was answered here , including the Digikey PN for the wheel.
