S.T. Dupont - Line d - Lighter - Gold-plated

S.T. Dupont Ligne 1 BS (Standard Lighter), dating from a production period between the 1960s and the 1970s
This model is immediately recognizable by the bottom configuration, characterized by the single cap of the gas refill valve positioned centrally and the small lever or lateral pin to interrupt the flow, without the flame adjustment wheel on the bottom (a feature of the BR models or later lines such as Ligne 2).
The flame adjustment in this model takes place inside, under the lid.
Lighters used with some signs of wear but nothing serious given its age!!! As in the photo, functioning.
