Help With Audiomeca Mephisto 1 CD Transport Top Lid Clamp Platter Replacement

I have been using an Audiomeca Mephisto 1 CD transport for some years now and lately the clamp platter at the top lid has been problematic. Does anybody know where I may be able to source this part?

Alternatively, if someone has a non working Mephisto 1 and can sell the platter as a part, that would be of great help.

Thanks and regards
