I believe this term has some application with teeth in Gearing, as in mechanical engineering, akin to the Metric Module, diametral pitch, and number of teeth per inch, ratio, etc. obviously model gears are made up before production models- those used on gear-making machines are sometimes called master gears- the blanks are cut after the master patterns, so to speak, could also be model, maybe Module-which refers to metric gearing.
