Any Pilot fans want to help this newbie out and ID this pen? Ive found other images of it online, but cant find a name. Also, is there a way to take it apart to clean it? Ive soaked it several times now in the ammonia/water solution and Im still getting starts and stops (see writing sample). It was seriously filthy. If I cant clean it myself, who are our Pilot specialists in the US? It doesnt need a grind so it doesnt seem to make sense to send it off to Mike Masuyama. I actually like it a lot when it wants to write. Super flexy. Thoughts? Shawnee
