I received this pen (it is a Slim Line, correct?) recently and the previous owner must have glued the section into the barrel - it won't budge. I've tried lots of soaking, ultrasonic cleaning, heat, and even penetrating oil but no go.
Can the nib & feed be pulled out? If so, perhaps I can soak more with liquid getting to the other side of the threads and/or put some penetrating oil from the inside or something else.
When I got it it had some ink and it really wrote beautifully. I was thinking it would be the perfect pen to carry with my notepad in my bag. It would be nice to fix but I'm about to give up ...
