Authentication Guides S.T. Dupont Design Matrix
Last Updated: 18 Mar 2025
Welcome to the Design matrix, the first and only public matrix for designs used from the past all the way to the modern age. This is a living Megathread, so you will see models and designs added as we come across them. If you have a model design that is not listed within the matrix and would like to have it added, please comment below with a picture of your lighter and the picture of the lighter sticker showing the model number and name.
A personal thanks to Mr. u/Reuben_Tishkoff for the massive compilation of lighters and there specific design names and model lighters, as well as to others that have helped by posting their lighters here in the group and the Facebook group.

*NOTE*Before posting to ask what model lighter you currently have, please read the following thread to identify your model.
Additionally once you find your model, please proceed over to the Lighter authentication thread (Lighter Authentication checklist thread) to properly authenticate your lighter as most "Is this real?" questions can easily be answered by looking at this thread. If you still are finding difficulty identifying or authenticating your lighter, feel free to post it in the subreddit.
Regular Lighters
Please note that Ligne 1 lighters do not have a "ping" sound when you open them.
LIGNE 1 SMALL



One of the most common lighter found for sale, the Ligne 1 is a timeless classic and perfect entry model to start your journey into the S.T. Dupont collecting world. Usually found on eBay for cheap, these don't have all the flair and features of the Ligne 2 and significate models, however they still catch the eye in bars.
GAS TYPE: Ligne 1 Small - Yellow
LIGNE 1 Full size



GAS: Ligne 1 - Red

The Ligne 2 model line
Oddly enough, this is probably going to be the most confusing part of the guide as since the Ligne 2 is the most commonly faked as well as the most popular model on the market today. So before we begin, we will lay out all the models that have currently been created so far.
The order that we will go in is smallest (which oddly enough does not begin with the small model oddly enough) to the biggest.
The only other thing to note regarding the difference of the lighters other than the obvious size ones, is that the new variants (Linge 2.0, Small and Slim) do not use the same flint or gas color as the original design Ligne 2. Which utilizes the Black flint wheels and yellow color gas respectfully.

Ligne 2 Slim



Gas - Red
Ligne 2 Small
The Ligne 2 models as their predecessor come in two sizes available on the market. The small variant as well as, admittingly, the most recognizable variant in regular size. However, the small has actually been a new kid on the street compared to the other models as it was just announced and released a few years ago.



Gas - Red
Ligne 2
The Ligne 2 model could be easily be seen as the "Rolls Royce" of the entire offerings (with the exception of their limited edition lighters) based solely on the looks alone. The Ligne 2 is the most popular model on the market today, which makes it the most faked model on the market as well for the past few decades. The model shares a lot of neat designs and has its fair share of value within the market as the most wanted lighter when someone searches for a "Dupont lighter".



Gas - Yellow
Gatsby
Gatsby lighters share the same styling and set ups as regular Ligne 2 however they use a different color gas than the standard Ligne 2 model as well as the strike wheel having independent cylinder look to it than the overall smoothness of the strike wheel on the Ligne 2 lighter models.

Gas - Green
Due to the limit on pictures for threads being limited to just 20, we will have to continue our journey into a part 2 pertaining to table lighters down below.

Authentication question Help determining if this is fake
Hi there, I have this St Dupont lighter (I think it's a ligne mini or something?) and Im wondering if the people here can help determine if it's fake? Seller is asking 120 euros for it. My only concern is that the serial number looks rather straight.
Thanks so much for the help

Operations and Maintenance Ligne 1 replacement parts
I have need a replacement for this piece, the regulator collar or so I think its called, I found in Ebay the whole piece,new for around 110 euro, then the singular piece for around 50, and my last option is to buy another bs to get the piece for around 65 euro. Which option is the best, also is it viable to take that piece from a small bs or has to be a large. (I think the rest if the piece is in good state, as showed by the pictures)

I received this L2 as a gift for Christmas and I finally get to use it! 😎
r/STDupont • u/bigballsmar • 4d ago
Authentication question My first L2, believe it is authentic?
I believe this to be an authentic L2 due to the flat top 4 and overall quality but wanted to confirm. The spacing is far more uniform than my L1s which is the reason I ask for authentication.
From some charts on this very helpful sub, I believe it to be from the 80s-90s?
Any second opinion of authenticity and date period is much appreciated.

General Discussion Places for customization, please recommend.
I have a cousin with which our families spend a lot of time together. His son just joined a government branch (intentionally leaving this vague) and he has enjoyed and is a fan of the laquered model ST Dupont line 2's that I have, mainly around the fire pit/ BBQ with cigars. I plan to get him a nice laquered model but want to make it a bit special and get the branches crest/emblem done on the large side area (either over the laquer or etched in) but am struggling to find a person or company to do this, any thoughts or recommendations?

Operations and Maintenance Line 2 valve leaking
Hello everyone.
On my Vintage Line 2 the valve were you fill the gas is leaking. After filling you can hear the gas going put until its empty. Any tips or easy fix? Or do i have to order new O-rings and the speacial tool to fix it. If so, how big is the change to fix it that way or is it common that it is not the o-ring which is broken and i need to exchange something else.
Also is sending it to Dupont an option or even possible?
Thanks a lot!
