There is not much I can say about Bob McCulloch, as I did not know the man. He was however responsible for many advances in technology, and moving London Bridge to Arizona. How many homes stand and documents exist because of the saws he created? All I can say is I wish that there were more Americans helping as much as Bob did to industrialize the country. The picture above shows Bob testing a saw, which I believe to be a 3-25 or a Model 47.
