Does anyone know of Daniel Steiger fountain pens? They appear to be a watch/jeweler for men, and must have made some branded fountain pens at some point. I got one as a gift around 2010, and need a replacement nib/feeder, but can't find anything that fits and don't know what to look for in a generic nib/feeder anyway. If I knew the mfr of this pen I'd have an idea where to look, or if I knew how to know what size nib/feeder I have, I could look for a generic. Thanks for helping!
