We had a Sun distributor machine that looked a lot like that one in my 1964 High School Auto Shop class.
Mr. Parker (shop teacher) did a show and tell one day using a distributor from a fellow student's 1948 Chevy. It spun all the way to 2500 distributor RPM with no point bounce and very little scatter.
