I found this interesting pen at a flea market. It bears the designer brand Yves Saint Laurent, but I've never seen this kind of stuff from them before. The pen is good looking, it's all metal and a little cigar shaped. The cap has a golden ring imprinted Yves Saint Laurent Paris, the clip has an incredible spring, and bears the legend Made in France behind. The pen is a cartridge filler. The barrel has a stop inside, which makes impossible to carry a spare cartridge. The section is metal too, with the exception of the screw, which is plastic. The nib, an EF to me, has the YSL logo engraved, but no other markings. I don't know what material it is, but it may be gold. All in all an interesting find, and a good writer too. Some pics:
