St Dupont Lighter Serial Number

St dupont lighter serial number 50? Blank kvitanc na oplatu gazu 1. DuPont lighter serial number 50 is located on the bottom.Each letter and number is printed separately so that each onediffers. I've been trying to research a way to verify the serial number but haven't had any luck. Dupont fuel is measured to specific lighters.

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.
