The classification of [[Conway Stewart]] models is extremely complex, although since the '20s the company started using names, all the pens were still identified by a number and sometimes only by that. In the '20s the top model (which will remain so for two decades) was the [[Duro]], a large pen, then there was the small and functional [[Dinkie]], and the economic [[Conway Stewart Universal|Universal]]. Other models made in the same period were the [[Pixie]] and the [[Dandie]]. | The classification of [[Conway Stewart]] models is extremely complex, although since the '20s the company started using names, all the pens were still identified by a number and sometimes only by that.
