The Sheaffer's Skrip in that Pelikan is older than the pen. Older than me in fact. I'd estimate by the box and label between 1949 and 1952 (then called "writing fluid", see pic below). I consider any ink from before 1980 "vintage" ... other folks may not agree.@nemo, please can you explain what is a 'vintage' ink? My understanding, based on the word 'vintage' is that it is not a fresh / recently made ink but dates back in time. Don't these inks lose their properties in time? Are they reliable in any pen or are there some pens which is best not to use them with? Thank you
