Hi. I need help to identify these pens. I have searched on the internet for some info but i didn't find any. The top one is a lever filler with "Skylark" written on the clip and a warranted 14k nib, and a broken sac. The lower one is a piston filler with Valero written on the cap and a Dauer Feder 12 nib. Is this something to worth fixing and keep? i got these and a unnamed pen with iridium point germany nib for about $12 Best Regards Pether
