Pirelli p slot centre cap

Hi all,
I'm looking for a couple of p slot centre caps, must have the raised Pirelli logo part no. 171601171A.
I know I'm unlikely to find any new, but if anyone has a couple knocking about, new or used, please let me know.  
I have one rear piece so if you have a face, that'll be fine.

Let me know what you've got, thanks.
