Dear FPN-ers, I recently restored an old bakelite lever filler fountain pen that, to my surprise, held a Pelikan nib. A firm XF nib as shown on picture. There is no flex whatsoever in the nib. I believe they call this an accountant nib. The big question is: does it belong to this pen or not? And if not, what is the make of the pen? There are no identification marks on it at all. I've never seen a Pelikan lever filler before, so it must be a mix of brands. Or am I wrong? Thanks for any suggestion! Ben
