And did Kenrick and Jefferson ever make a pen that wasnt labelled Superpen? I know there are a few different varieties of Superpens but I dont know if K&J Superpen should be separate, or if just Kenrick and Jefferson should!
Perhaps this list needs dividing under three headings:
Brand Model Manufacturer
Kenrick & Jefferson Superpen Mabie Todd
Conway Stewart CS550 Dinkie Conway Stewart
Conway Stewart CS240 Lang
Dickenson Croxley Lang / Dickenson
Parker Duofold Valentine
You get the intent..... it starts to clarify some of the type of issues Matt is raising.
Probably to big a task for one rainy afternoon ;-)
