I recently acquired an old and somewhat abused Pelikan Rappen. I suspect it's sound enough to become a writer again. As far as appearance, it will be a chore, as the end cap is either not original or the owner had somehow reshaped it. I understand from the estate sale that it was from the desk of a 94 year old. So in some ways the shape is now part of this pens history, and if I ever find a replacement end cap, I can decide then what to do.
My immediate need is to figure out what sort of sac this uses. This is an early model that pre-dates the piston filler type. Has a tube that runs from the feed, into the sac. I understand that the fill method would be to squeeze the sac. I guess I can just approximate the diameter and order a sac, but just wonder if anyone knows if the Rappen uses a particular sac ?
My suspicion is that since the end cap needs to be removed in order to fill the pen, the end cap I see if a homemade replacement.
Once I get started on this, I may take a photo history of the progress of my novice attempt of the restoration.
