Got a couple of these as they were advertised as 70mm so I thought perfect for the bonnet of my Z, they came and are actually 77mm 
These are not the flimsy alloy wheel ones they are proper domed roundels and look like a bonnet badge
I can send them back as the seller has accepted it was his measuring mistake but thought I'd post here first to see if there are of any use to anyone.
They are self adhesive 3M style tape and do not have the locator pins, I think they may actually be designed for a BMW motorbike
I tried to take a picture but its really hard to do with the light reflecting on the curve of the badge
