I have a Parker 15 that is a wonderful writer (my favorite bar pen) but it has a harsh and unsettling white barrel. Anyone know a source for a replacement barrel? By barrel I am referring to the portion of the pen that encloses the cartridge, my abject apologies if my terminology is incorrect.

I guess you can go to the Parker website, tell them the barrel got broken or something, then ask if you could order a new one. Available colors I think would be red, black, blue, green for plastic. There is also the stainless steel model. Or you can look for any Parker dealer, ask them if they can order one for you.
