Is this ST Dupont a fake?

[deschete]

I didn't buy it, but the seller is in Rhode Island. He's got a fair amount of ST Dupont items for sale, and a lot of Colibri. He says "guaranteed authentic" but also says "all sales final."

My thinking was that perhaps he bought the Colibri stock when they went bankrupt and possibly it's legit, but I am not sure.
