Sportsmen,
No winners yet, although I have received some partial correct answers. There is no trickery going on with this. I'd better give a hint, so here is the hard one. D is one of the fakes. Try looking at these from the perspective as if a Cinelli rolled up to you and what you would expect to "FEEL" if you looked at the badge. I think it really helps to look at it this way, and not just with your eyes. It is subtle, but perhaps a valuable way to look at things. Sheesh, I've practically given it away now.
The winner will get a wooden dish to hold your beer nuts, hand turned on the lathe by me.
Good luck!
