History of Roosa-Master pump development

[little1406]

I found this nice article about the development of the Roosa-Master injection pump and the important role it played in expanding the use of diesel power throughout industry and agriculture.

Apparently the design of these pumps was a great innovation over existing designs and the credit all goes to Vernon Roosa.

Curiously, the article mentions the first pump, Model "A", and then the Model "B" pump, and then the Model "D" and "DB" pumps.....but there's no mention of the Model "C".....!?
