ST DUPONT LINE 1 gold lighter authentication video 

Those lighters go for about 70/100 euro max. They work beautifully and last a lifetime, unfortunately the ligne 1 doesn’t ping as much as the newer ligne 2

Thats pretty neat. I never knew there was a market for vintage lighters. Thats wild how much those can go for. Something for everyone! Thanks for the knowledge.

Dupont lighters are the Roll Royces of lighters like Rolex is 2 wristwatches. I have the exact ligne one as yours, ser.# U8BE72 I wonder if the 72 stands for year made as in 1972? Anybody know? Great video 📹 Thanks

I also got a line 1. You can not take the part out for engraving. The screw is for the "Echo" plate

Good video. Been looking at trying to find a used line 1 or 2 variant but the prices are taking some getting used to.... I'd like to find something with original box and in good condition but a lot of rough lighters on ebay

What’s the range one should be paying for these vintage lighters on ebay in USD? Thank you

What liquid do u clean it with ?

a real Saint Marie would have a "ping" sound when you flick the lid open
