Conklin Crescent 40 pens are a wonderful mid-size vintage pens. These black chased hard rubber pens just don't quit after more than 100 years. We restored this one with a new ink sac. There are no chips or cracks in this pen, but you there are scratches, worn chasing and imprints, brassing on the clip and crescent. The clip is still attached, but we wouldn't trust it for any use. It seems weakly attached. The cap band is marked "14k 1/5." You will write a fine-medium to 1mm wide lines with its semi-flex Conklin #4 nib made of 14k gold. 13.5cm capped.
