Hi Ben, I think I must have just read your thread on PH about this without realising it was you (funnily enough I thought of you the other day when I saw your old car at a PH event).
The quality of what you're proposing looks great (especially the last one), and I'm sure it'd probably look perfect on the right car. My only concern (apart from copyright that I know you're aware of) is that to my mind it reminds me a little of a certain (80s/90s?) era when car badges were often all black plastic with a silver top. With modern cars badges generally being all chrome (I think) I'm not sure how it would sit against them (I'm guessing the newer car market is probably one of the most lucrative to chase, but that may not be the case???).
