What is the material it is made of?
While often referred to as “lead type,” type is, in fact, a variable alloy of 54-86% lead, 11-28% antimony and 3-18% tin. Antimony hardens the metal. Tin toughens the metal, counteracting the brittleness of antimony, as well as increasing the fluidity of the molten metal. The exact alloy chosen is based on the type of machine it is to be used in.

I’d say it is a “zero” rather than an “O”, if it matters. I see no relevance to Richard.
