Anyone know why it's so hard to buy a new 146 with an extra-fine nib? There are literally none available in either the US or France (I was traveling so I checked while I was there). Instead I had to buy a medium and send it into the factory for a nib replacement, but now I'm stuck waiting 6 weeks while they order an extra-fine nib from Germany. It's difficult to understand why it's that hard to get a pretty standard pen.
