Vintage S.T. Dupont Ligne 1 gas lighter, made in France, finished in silver plate with the elegant Micro Diamond Head guilloché pattern. This pattern features a much finer and denser diamond texture than the classic larger Diamond Head design, giving the lighter a particularly refined appearance. Details: Brand: S.T. Dupont Model: Ligne 1 Finish: Silver plated Pattern: Micro Diamond Head / Micro Pointes de Diamant Made in France Serial number individually stamped on the base Gas lighter with flint ignition Fully functional: ignites correctly and produces a strong, stable flame Condition: Very good vintage condition. The silver-plated finish remains bright and the fine guilloché pattern is very well preserved and clearly defined. There are some light signs of age and use, mainly on the base and edges, but no significant damage. The mechanism operates correctly, as shown in the photographs. Please examine the photographs carefully as they form part of the description.
