Hello! Here are my Rappen and IBIS collections.
I am sorry for poor picture quality.
AS you know, "Rappen"and "IBIS" were brands of Günther Wagner as well as "Pelikan".

IBIS with CN nib
There were much more versions in Rappen and IBIS than I thought.
Very nice thank you. Let's please see your 100 - 400s too!
