Greetings. I recently picked up a 333 1/2 for less than usual, knowing there would be issues. The body, section, and cap all look fantastic. The nib will need a little attention, but is salvageable and incredibly flexible. But the feed is clearly not original and undersized. I have the equipment and ebonite rod stock to create a new one, but I don't have any idea what the upper part (underside of the nib) looks like. All I can find is images of the underside of the feed. If anyone has any pix of one 't would be deeply appreciated. Dimensions would be even more appreciated. Best, Nick
