So here is what Steve turned me onto this morning - a dealer car emblem from London Motor Products which is where the Black Car was sold new. Now to decide whether it goes on the car? Doesn't say whether it is studded or not.
This eBay seller has a ton of Canadian dealer car emblems. Here is a link to one. If you have a car from a Canadian dealer it might be worth checking his other items.
