Not sure where I picked this one up. Wing Sung 612. Writes like a dream. I love the cheap fountain pens as much as anyone. It usually takes a few seconds of scratching to get it flowing, but once it starts, it's something to behold. Fine point and tasty as they come. I remember looking up online where I bought it, but now the details escape me. Just put in a fresh load of Levenger Ravens black and off to work.
