Very nice and collectable Parker ''51'' Vacumatic Blue Diamond Fountain Pen in beautiful Cedar Blue colour. No dings in the steel cap; no personal engravings. It has a solid gold Fine/Extra Fine nib that writes very smoothly. The filling system is not operational anymore. The fountain pen has a very clear imprint in the bottom of the barrel, which indicates that it was produced in the third quarter of 1946: 'PARKER ''51'' Made In U.S.A. 6. '. No imprint in the capband. Some loss of the guilding on the clip. Beautiful pearlscrew in the top of the cap. Please take a good look at the pictures as they are part of the description. The fountain pen will be shipped in a black leather pen pouch. I will ship Registered and Priority.
