I have several pens I want to get repaired. First is one of those Filcoa pens that are the tiny fountain pens. I want it gone over to see if it can be used. Probably needs resacced. I may just sell it as is. Next is a Paul Smith by Cross. The cap comes apart. I could do it myself but I don't have a small enough allen key. I need a new nib for a Taccia Imperial Portuguese. I also want to get an extra converter for it. Where should I go?
