These lighters cannot use the double flame and/or pipe fuel nozzles that the later Ligne 1's and ligne 2's can accept. Old bottom w/slotted fuel valve oldbottom.jpg (10.72 KiB) Viewed 101831 times These are pretty common and generally aren't worth as much due to their age and older mechanism. Note that there's a few generations of Ligne 1's, the oldest have a slot on the fuel cap and a older style flame adjuster valve. Damaged/heavily used ones can sell for extremely cheap sometimes - $30 - 50. New old stock can often be found for $200-400 range. Ligne 1 Ligne 1's are often sold between $50 and $250 used for most common models, depending on condition. These should not be used as actual pricing guidelines, but rather as minimum prices to use when avoiding fakes. Pricing Estimates All estimates are USD and are for reference purpose only. Serial numbers are generally 6 or 7 digits long but never longer and should end with a number. Anything with FK in the serial number is fake, as well as lighters with the serial number 06D08A8 or similar (a couple letters/numbers swapped but otherwise the same). Generally the fakes with lacquer look somewhat plastic-like in the pictures, almost looking too shiny.Īlso if it says lacque de chine and it's not lacquer, it's a fake. Limited editions often don't have emblems either, and will have an issue number rather than a serial number, such as 0001/1000. Generally the ones with no emblem come in the newer black/purple boxes although that may not always be the case. I have not seen any fakes trying to emulate the older style emblem so generally they are trying to copy the one with just a D and the wings. The newer lighters have either just a D with wings or no emblem at all. I'd expect most older style ligne 2's to have the older emblem, which has dupont spelled across the bottom. They will not get any higher and if you notice the ridges getting higher towards the hinge side it's probably fake. On some real ligne 2's it looks like it's slanting back up if the photo is at a slight angle, but they should taper downward and stay relatively the same size until the end. Vintage.JPG (16.4 KiB) Viewed 102121 times This isn't an entirely reliable way to tell unless the picture shows that portion of the lighter clearly. I've been able to use this method of determining fakes without having to actually see the bottom of a lighter, which is useful if you're buying online Visual Cues. A real L2 is always a downward slant and never slants back up again. The tell-tale sign is the lettering on bottom but I've noticed that on a lot of fake ligne 2's, the ridging on the top of the flint cover is almost 'u' shaped in the middle, kind of like a ligne 1's, but to a lesser extent. There's been numerous guides out there to fakes and the best way I think is to look around for some pictures of fakes and compare them side-by-side. This is a general buyers guide, describing not only counterfeits, but things to look out for in general. Please check-out our other active auctions by clicking on username 'Avrinet'.
