Is this ST Dupont a fake?

I would be skeptical of a vendor who has many Duponts for sale. I got taken from an ebay vendor selling quite a few Dupont lighters, which turned out to be fake. You should be able to tell based on what you paid. If the price is too good to be true, it probably is. But I don't have enough experience with them to determine if yours is real or fake by looking at the picture.
