The SEVEN cylinder engine depicted is absolutely not a model of the 80 horsepower LeRhone 9C engine as that one as the number implies had NINE cylinders. I believe the seven cylinder variant was under 70 horsepower although I've never seen any photographs of an example of one.
That said, I have however worked on real 80 h.p. LeRhone 9C's .
CAN WE please TRY to get some of the things on here historically accurate?! Thanks.
