Hi friends,

I’ve had this vintage S.T. Dupont lighter for a while now. I believe my great-uncle bought it in Paris, and when I got into cigars my mum gave it to me.

From what I’ve been able to gather, it seems to be a Ligne 1 small model from somewhere around the late 1960s to early 1970s, but I’d love to hear more from the experts here.

The iconic “ping” is still there a little bit, but definitely not in its full capacity. The hinge and lid alignment actually seem quite good to me, so I’m wondering whether a careful cleaning and some basic maintenance (preferably without fully disassembling it) could help bring some of that resonance back.

The flame performance also seems a bit weak. I suspect regular butane may have been used in it at some point in its life, which might have left some residue in the internals. Right now the flame starts relatively large and then quickly settles smaller after ignition.

Would love to hear your thoughts on dating it more precisely, and what could realistically be done to restore some of her former glory while keeping things as original as possible.

I especially felt like pleasing my citizens today. Was able to get the bathhouse happiness boost up to 28. Has anyone gone higher yet?

Found out that for each of its separate elements, there is a specific size which gives a bigger boost (e.g. hot pool becomes 'large' when its 3x3+4 (maybe not the most efficient set-up, idk), at which point it gives a +6 bonus instead of the +1 of a single, small hot pool.

Large library 2x3, +3 (+3)

Large cold pool 4x3 (+6)

I think for garden/gym large = 2x3 (+3 each)

Additionally, you're able to stack multiple of these larger entities per bath complex (I did one large and one medium cold pool, but I think you can have multiple libraries and hot pools as well. Does not work with gym/garden.
