Hello, or perhaps I ought to say, 'Bonjour', This French Watermans pen, possibly a Ligne 60(?), has a filling system that I haven't come across, before. http://img.auctiva.com/imgdata/1/2/5/3/2/1/0/webimg/827324423_tp.jpg Dipped in ink, the 18k nib writes beautifully, but I can't fathom out how to fill the 'cartridge'. The aluminium cartiridge has a hinged, brass tab at the end. Does the cartidge screw, or pull out? I'm reluctant to use force for fear of breaking something. http://img.auctiva.com/imgdata/1/2/5/3/2/1/0/webimg/827324814_tp.jpg http://ti2.auctiva.com/web/supersize/clicktosup_000000.gif I'd be grateful of any guidance you can offer. Thankyou. http://img.auctiva.com/imgdata/1/2/5/3/2/1/0/webimg/827324854_tp.jpg http://ti2.auctiva.com/web/supersize/clicktosup_000000.gif
