Hello everyone: I have a Sir Charles Godfrey supercharger on my TC engine. I see that this was the forerunner of the Marshall-Nordec supercharger according to the W. E. Blower book. It is a "Roots" type. This SC has been unused for nearly 25 years and I believe the oil seals are in need of replacement as it allows engine oil to get into the combustion chambers, thus producing a cloud of white/grey smoke. As I am not in the business of fogging roadways to kill mosquitos, I would like to get this SC repaired by an expert, preferably in the USA. Any sources known to you?
