Can anyone share references to articles and research about sources of celluloids that manufacturers used to make pens and pencils in the second quarter of the twentieth century? Put simply, who made the stuff?
I'm looking for detail, because I want to trace a certain pattern used by several American and European pen and pencil manufacturers.
