I finally created an account today after browsing these forums for the last few years. I am new to vintage pens, but not fountain pens in general. I often go to antique stores to pick up older pens, and can complete simple restorations. In this case I believe I have met my match.
I found this Doric for $20.00 at a local antique shop. Since then I have done a simple cleaning of the pen, and was able to free the plunger, along with the adjustment slider. The nib is very whet, and uber flexible... but is as sharp as a knife. The second issue is that the seals seem to have given out, and it refuses to drawing ink. The internal mechanism seems to be beyond my repair expertise, and at this point I don't want to damage the pen because the body is in almost perfect condition.
Who should I go to that could repair this pen? I'm a student and don't have hundreds of dollars to spend on this, but at the same time I don't want to break the pen of my dreams.
