I actually have an other form of character storage drum: I guess it would be called a character storage disk: a glass disk holding the font glyphs(?) through which a light beam would expose the character onto the photo-sensitive paper. I can send a picture of it if anybody is interested (and when I unearth it as I recently moved to Seattle)....
