I am really in need of some help as I am at a total none starter with these two onoto pens I have come across in my "to repair" collection. I was originally going to trade them as "pen for repair" but I have been dipping with the nibs and they are fantastic! I just love the flex and want them for myself. I`m really struggling - I have read all about plunger fillers on Richardspens and also read this full article on how to strip and service an onoto, yet I`m still none the wiser! If the article had pictures I`d be fine but as a block of text, I`m confused:
OK, so here are my pens:
And one of the lovely nibs:
Ok, so I follow the instructions in terms of screwing off the nib and I meet my first problem - with one pen I have a little plunger sticking out the end of the pen (when the plunger is pushed in) but on the other one I don`t see the plunger and there is nothing to get hold of but there is a little washer sitting there. So one of them looks like this, you can see the plunger sticking out:
Following the instructions - the plunger can be unscrewed and removed from the rod:
Quote from the site above, at this stage: 3. The cone assembly and plunger are now detached from the rod and comprise two parts held together with a hard rubber pin. This is usually a friction fit but sometimes threaded (right hand thread). Knock out the pin with a fine steel punch and separate.
So is the picture above of the cone and plunger - I can`t see any pin?!
And from here I can`t follow any of the further instructions (on both the "front end" and any of the "back end"). Has anyone any idea where to go from here and what repair parts I am going to need, possible a source for them?
The other pen seems to be even more of a challenge, with the nib off and looking down the barrel, even with the rod pushed in, there is no plunger sticking out the end, now is this a different type of pen or is the plunger missing - can they be replaced?
I would really really appreciate it if someone could lend some advice. I realize I could send these off for repair but I want to try and achieve this myself like I have with a large number of lever fillers and also my P51 aero. I enjoy my pens even more with the knowledge that I restored them.
Any advice would be more than appreciated - can anyone else follow the instructions? Where do I go from here?
