I am looking for a funnel or a connector that will allow a customer to make a desk set using the junior series. Funnel would work with jr gent ballpoint.
Years ago, there was a part that could be substituted for the clip holding "top", which had a pivoting connection to a base that screwed into a wood base you would make for a deskset. I made a couple of these for my own use, they worked ok for the rollerball or fountain pen.
