You think the gold parts could be solid even though it isn't marked? I've seen some that were real gold but they were marked at the bottom of one of the narrow sides. I'm assuming it is plated if any real gold at all. The lighter is gold in color with black inlay but It isn't marked with any metal content such as K (karat). It also looks as if it has been used pretty well. And since it's a combo laquer and gold (I am assuming gold) and not full gold, it's weight in gold value is decreased. You don't have any papers or boxes with it. I have never seen a slotted fuel cap on a fake However, for resale value it's going to be very low.
Vintage Ligne 1 Dupont's are rarely if ever faked 3. The stamping of the letters is a bit crooked as it should be for a vintage Linge 1. I can't really tell from the pics, but is this a gold lighter? If so, I am going to go out on a limb and say it's real based on a few things: 1.
