I'm not sure if this is the best place to post this, but I'm looking for a replacement nib and feed for my Wearever I don't know what model. It's a pen/pencil. I understand that these are relatively common and not of the highest quality, but I do think it looks rather neat. I do know that the current nib is after market that reads Moore Iridium Duo-tip not the smoothest writing nib, also the feed likes to keep me high and dry. I don't know what types of nibs would fit this sort of pen so I'm asking you guys. Please help me with this if you can.
