Dunn-Pen...no Threading On The Little Red Pump Handle

[Keyless Works]

I came across what appears to be a decent example of the Dunn-Pen. The body looks to be in good shape but I notice that with the pump handle extended there is no threading to screw the handle into the back of the barrel; is this normal? The other Dunn-Pens I have seen (2-3 in total) have threading on the red handle.

 

After asking the seller (not a fountain pen person) some questions, if you turn the pen vertical (nib pointing up) the red pump handle will come out about a centimeter.

 

The pen is cheap and I am wondering if I should risk it. If there should be threading then it's a deal-breaker.

here's the relevant passage: "Today their main drawback [besides being difficult to fix] is that the red filling knob is usually found with broken threads where it goes into the pen barrel."

Not that I have an answer to your question, but perhaps a new Dunn - cunningly called the New Dunn - from Richard Binder may be an option? I have 2. They are my favorite writers - just perfect in size, heft and writing.

I have a New Dunn, one of my favorite owns I have. I also have a small, old vest-size Dunn. The threads are broken on that one, but friction keeps it in fine.

 

As for your dilemma, I would think that if the filler slips out every time you put it in your pocket, sooner or later you are going to have a mess. It'd be damn near impossible to fix too. I would pass, if I were you.

Thanks for the advice!...it's a pass for me. I love the look of the new Dunn pen but it's a bit pricey...I will keep a lookout for a second hand one.
