That is definitely an Ink-Vue demonstrator model. Personally Ink-Vues are my favorite pen of all. I have restored a number of them now and honestly I find that no other filling system works as smoothly or is as nice to use as the Ink-Vue (except maybe a really good snorkel). If you need any tips on restoring let me know. A lot of restorers refuse to work on the Ink-Vue as the plastic is notoriously brittle but I have never had any problems and have 6 in my collection.
