Parker 51 fountain pens are the corner stone of any vintage pen collection. This is likely a married combination. While there are plenty of black 51s with gold-filled caps, as best we know the gold-filled caps with amber jewels only went with the cordovan-color pens. This pen is in great working order, but it has its share of wear and scratches. We restored it with a new diaphragm. Clearly this was someone's well-loved writing companion. You will write a very nice, smooth fine line with its 14k gold nib. This pen is 80 years old according to its 3rd quarter date code from 1944. 14.3cm capped.
