My first vintage Sheaffer pen was a Triumph 550GT pen, that needless to say, wasn't equipped with a Triumph nib. But it was thanks to this pen that I found out about Sheaffer's legendary conical nibs. It's been a while since I've been under the impression that all Sheaffer conical nibs were denominated Triumph but just yesterday I got a Sheaffer Stylist MkII pen that sports a nib that is a conical one but seems to be referenced as "Skripsert". Can anyone clarify what defines one or the other nib? Thanks in advance!
