I've got one of them too, and its in _exactly_ the same condition. I found
it when I replaced the head on my Ur-q, though I still haven't worked out
how the PO's 'Tuning' company managed to miss it six months earlier.

Part has been superseded by a number that I can't find any record of - all
that I remember is that the replacement was made in Mexico.
