I saw one of those Mosquito injectors over 50 years ago. I thought it was strange that the firm used the name of a Catholic boy's high school. It was on the south side of Milwaukee and most of the students were from Polish families. You were high-class, in those days, if you went there.
Of course, that wouldn't fly today. Even the trade schools have to be co-ed.
