Find best value and selection for your Vintage Dupont Lighter Made in Paris France Serial Number 3909CP search on eBay. World's leading marketplace. Mar 04, 2015  Lovely lighter! There are a bevy of S.T Dupont lighter fakes out there. It seems the only true way to tell if one is a fake is the look of the Serial numbers. The numbers should not be aligned. Each number is hand stamped separately. Somewhere I read that if one calls Dupont and give them the serial number, they will tell you if it is.
