1950s Parker “51” with a Kosca gold filled guilloche overlay. This is an exquisite pen. Although the gold contant is not marked, it is simply marked laminato oro, it is serial numbered. The pen pretty much speaks for itself. The fishscale pattern is very fine and there are three plain bands around cap and barrel. The pen is flawless save for a 2 mm crescent disruption to cap. Inside it is a Parker “51” of course. This pen will make smeone very happy, unless I decide to keep it for myself. The nib is an uncommon medium. $395.00
