Hey everyone: I just saw Max's post and slapped myself for not thinking of posting here. I need a *No. 4 Waterman Ideal New York Medium to Broad FLEX nib to purchase or trade* for my pristine F semi-flex version (this is my 82-year old mom's pen, which she got as a girl from the original owner, and she can't really write with the semi-flex F). I would be willing to do a trade + cash (I realize the wider flex nibs cost more), or an outright purchase. I would like a nib in really near mint condition, lots of iridium, etc. Thanks, Eric
