I just re-read your original message and it seems to imply that you need the whole badge. I would try contacting MGFNTFBITZ who seem to have an enormous stock of new and 2nd hand parts. They may have a decent 2nd hand badge.
My original badge had a good chrome surround but it had seriously delaminated. The paint underneath was peeling away. I just scraped all the loose stuff off, gave it a wipe with meths, and stuck on the insert. If you examine it, it can be seen that it is not the original but you have to look pretty closely.
