I own one of these, purchased in 1973, manufactured before that. I gazed at it in the local jewelry shop for several years as I saved up the money for it. After reading the description, I refreshed the ink in my 149 and it writes like a king. Wow. Of all my pens, and I own and use and love many, this 149 is the top of my collection. It's an extra-fine, but it writes like a fine architect grind, wider horizontally than vertically. A tiny bit of flex lets me get a heavy ink flow when I want it. It has absolutely no starting issues, even after weeks of neglect. No flow problems, never a skip or railroad. It's really kind of amazing. I have plenty of great, expensive pens, but none of them have the absolutly flawless, reliable, never-distracting performance of this 149.
