Some vintage pens get a little confusing. We think that this is an Aikin Lambert pen due to its inconclusive 14k gold nib. Click the headline for a close-up. The nib imprint says "AL Co." We are thinking that is for Aikin Lambert. However, it also is possible that this is a replacement nib. The only clue on the barrel is the "Glide" imprint. Nice repousse barrel bands. Unscrew the section easily for an eyedropper fill. We wish this pen had a cap. You will write a stunningly smooth-gliding fine line that flexes to just over 1mm. 12.4mm.
