Hi everyone, I've just received this pen from an auction, advertised as a 3776 from the 80's with a 'unique' clip. Supposedly a fine nib, it writes with a very european medium line (although, I have to say, very smoothly). There is no Platinum branding anywhere on the pen itself (lightweight black resin) and it has a suspiciously modern 'plastic insert' push-on cap. I can't find any images anywhere of this kind of 3776 nib design, especially that logo beneath the 14k stamp. Nor the feed. Also the 14k stamp has a full stop after it ( 14K. ) and the air hole is circular as opposed to heart shap
