I went to Richard's site and read about his. Says triumph nib. Well, probably short one.
I could not find much on Jim's site or I am looking in the wrong place. Perhaps the nib in the Imperial II is close.
Someone has one that has a nib similiar to an Imperial I that is at Jim's site.
So, I am wondering if this was a franken pen or did sheaffer put different nibs on this pen.
