Penexchange

Friends,

I happen to own an early M400 with a friction fit nib-feeder unit. The seller said he didn't know that it was a friction fit unit, and I didn't discover it immediately.
The pen is green-striped, with an F nib and works great. The nib unit is easily removed but has never spontaneously come off. The problem is that it doesn't "sing" for me and on the go I don't feel completely safe and comfortable with it.

Of course I have paid about 125 USD for it once, but the main thing for me is that I want the pen to get a new loving and caring home. I'm open to negotiations, perhaps a good trade, with a M200 F or EF, Café Creme or Cognac or a (M)400 nib unit EF?

Please take this under consideration.

Sincerely

Lennart Wennberg

I own an M400 too, really good.

One of the quickest and simplest methods to tell the two models apart is perhaps by looking at the feed. A hard rubber (ebonite) feed comprised of four vertically arranged fins was installed on the 400. The plastic M400 feed is made up of numerous longitudinal fins.

Thank you for providing such useful information. I've been having trouble coming up with many questions about this topic. I'll stick with you!
