Anyone Seen This Feed Before?

[Greenie]

This is on an eyedropper pen I recently acquired. I have not seen this type of feed and I am hoping someone might be familiar with it.

 

Over and underfeed. The overfeed seems to be one piece machined along with the rest of the section. The underfeed is scooped out and slides into feed. There is a step on the underfeed that catches the end of the nib shank so the minimal underfeed depth seems to be set. Of course, it could have been broken or shortened sometime in history.

Are you sure that the underfeed is supposed to catch the back of the nib? Because I've never seen nor heard of a nib that doesn't use a proper underfeed. An underfeed that doesn't reach close to the tip of the nib doesn't really do anything at all

It might be broken off a bit short. And the sides can easily be trimmed back so the feed sits better, a bit further out on the underside of the nib. I am hoping someone is familiar with this and has pictures, or even a lead to point me to perhaps a patent.

 

On the other hand, it could also be correct. Such as old Wirt overfeeds. That Wirt design is just a plain flat piece that wicks ink on to the top of the nib over the slit. No underfeed at all.

 

This design could just be another simple flat overfeed. However, one that does not extend into the barrel. Therefore the underfeed would be less of a feed and instead the part that brings ink into the section, to then be fed via the overfeed.

Any indication who made the pen?

The slightly irregular shape at the end of the underfeed makes me wonder if it was longer, once?

As you say, may have been modified or damaged?

 

Looks interesting, though. I see you're restoring it? Have you had a chance to write with it, yet.

 

The action of gravity and capilliary action working together help me understand an underfeed, rather than an overfeed.

I've had a few pens with both (over and under) but never had a pen with just an over.

 

Thanks for sharing. Good luck.

No indication of a maker. The pen has alternating mother of pearl and abalone slabs from end to end except the decorative gold ring on each barrel end holding the slabs. It is a design that leaves no room for a maker's mark, and the nib is unmarked as well.

 

I haven't filled it or written yet. I was hoping to find out more about the underfeed first to see if it needed a bit of restoration as well.

Perhaps the overfeed is the ink delivery system. No harm in filling it and giving it a try. It sounds a most interesting and attractive pen.
