What I do when my wife looks for plant racks for the garden in antique stores is ask to see pens, and its rarely rewarding. This time is was exciting. A sad looking pen, but the blunt rounded shape called for a closer look. Nib looked to have been polished many times, and I could only see K, (I really need to find time for cataract surgery). I have only modern Pels, but Ive seen 100s online. At home, I can read the nib with my loupe, and look at webpages, and its definitely an 100. Looks too delicate to do more than remove the cap. Now Its residing in a tray, and I refrain from touching it. Again, time, prevents a photo. I promise to take a photo when I send it off to rehab. Just read http://www.caprafico.com/pens-88/pelikan-pen-restoration-275 and Im enen more afraid of touching it. Any suggestions?
