I've been buying and selling them for a while & I don't know where you can look up the serial numbers, if at all. It would be very useful but on the other hand, if it were easily accessible, there's nothing to stop the determined faker from copying e.g. Ligne 2 models & using genuine corresponding serial numbers on them. ST Dupont may have a record of all the lighters they've produced. Ligne 1, 2 and ' D ', Gatsby, Urban, models have hand-stamped serial numbers, not machined. They are irregular and not perfectly aligned.
The serial number, - each letter and number of the original is printed. The first gas lighter made by ST Dupont was introduced in 1953 under D57 code mark,.
This is a short guide on how to quickly determine if your S.T. Dupont Linge (Line) 2 Lighter is authentic. These are the lighters most 'faked' on Ebay. There are also counterfeit Gatsby lighters I have seen on Ebay as well. Usually persons selling have little to no feedback, 100 points or less.
A lot are from China, but it isn't hard to setup an account to make it look like your somewhere your not. Also the selling party might not even realize that the lighter is a fake, the Line 2 counterfeit lighters look exactly like real ones, depending on model/design being counterfeited. If the selling party does not picture the bottom of the lighter, where the serial number is, its Probably fake. If it looks the the numbers are lined up perfectly, if they are engraved, its fake. ST Dupont stamps their lighters with numbers not aligned in a straight line, some numbers looking higher or lower then others.
Counterfeited line 2 have serials engraved in a straight line. Even if your lighter doesn't look like one of the lighters pictured below it still could be fake. Fakes change on a regular basis to try to keep up with ST Dupont.
Top instructions (yellowish) are genuine warranty card on the left is genuine, its not as dark as the fake Its also possible to place a fake ST Dupont lighter, in a genuine box. I have seen it done several times on Ebay. G struve veselaya pesenka. Sharp ar m351u scanner driver reviews. The insert in the gift boxes have sharply raised angled edges, genuine boxes have only very slightly raised edges, almost hard to notice in most pictures. Also you can notice the color difference, though my camera isn't perfect when representing true color. All pictures the box to the left is genuine Counterfeit Line 2 lighters are heavier then real ones.
MOST IMPORTANT, SURE SIGN! If there is no paint underneath the Cap for the refill valve, its almost definitely fake, though its possible to be a replacement with no color dot. All Line 2 Lighters have a yellow paint dot underneath the cap of the refill valve representing to use the gold Dupont Butane refill can (see picture below). If it comes with a brass butane adapter (unless it screws in) its probably Counterfeit. You should need to screw in the butane canister refill, and we (as well as ST Dupont) recommend to only use Dupont Butane gas in ALL ST Dupont Lighters. Its also possible for the paint to have chipped off inside the cap, but if that has happened, you should be able to find some pieces of the paint in the cap. Line 2 lighters now retail for over $700, most $900 retail.
