There are a few that collect and use vintage inks but not many. Mostly you will find those that collect the large bottles half full that were used to fill the ink wells in school. The interesting part is the ink was made so well that is did not spoil. Bad ink will get a film and a mold on it. There is a chemical that is part of the ink formula that inhibits the growth of mold. From time to time you will hear of a modern ink where there is a bad batch because of this chemical not being mixed correctly. Anyway back to the question at hand, should you buy the ink to re-sell to collectors. The one thing that caught my eye was you said in the original packaging. That is where you will find your interest. If you get it cheap you can easily put it on fleabay and will do well with it. Don't put it all on at once put on one bottle and see what it does then go from there. No need to flood the market if you can get 2-3 people bidding against one another.
