Sickle Bar minneapolis no. 6 parts

[lowelljohnson]

i pulled a no. 6 sickle mower from the brush and am trying to get it working. the pitman is broken and the cup end is missing, "may still be in the brush" i am having problems finding a good parts source. im looking for the pitman and cup end.
thanks lowell

now that it is cleaned up some i see it is a minnesota no. 6 mower. someone told me they were made by the prison inmates. but i dont see any part listing for a "minnesota" can anyone tell me anything about this? there are part # on a lot of the parts but they dont match any parts list i find. are they just a generic parts and any # 6 pit man and cup will work?
