I have this Waterman fountain pen. Here it is capped. Here is is uncapped. Here it is in a close up of the section/nib/feed. I probably need to ask about how to fix this one in the Repair forum, but I'd like to know what it's called. The nib is attached to the feed in an unconventional way. Sorry the photographs are crummy and done with such different lighting. I am not a photographer. Thanks for any help.
