Recently I've been thinking a lot about windows. No, not those windows....I mean ink windows. When I first started my FP obsession, I never noticed them before---being too busy being awed by the wide array of nibs, finishes, and shapes of fountain pens. But now that things have calmed down (somewhat), I realize that I really like them. They're simple, functional, pretty things that remind me of stained glass when you hold them up to the light. They're not as blatant as, say, demonstrators (a personal dislike of mine), but petite, light, and floaty. And so useful, too! My MB 146 has a lovely blue striped window, and I'm currently hunting down a vintage Aurora 88 after seeing a picture of it (& its window) in someone's daily carry on FPGeeks. I know the modern 88 has a nice window too, as well as some Pelikans...(not talking about the tortoise ones, which have semi-transparent barrels...that's a rather different type of "window" than the ones I'm thinking of). Anyways, the point of this thread is, what do you feel about ink windows? And can you recommend any more pen models with them so I can Google image for some eye candy?
