Here are a set of "solex center lube camshafts" for Porsche 901 and 911. These parts numbers (90110511001 and 90110510901) check out for the earliest 901 and 911 cars about October 64-March 66 when they used solex carbs. I do not see any damage but I notice the small oiling holes seem to be missing but I think the center hole going all the way through the camshafts is still there. My theory is these have been welded on/worked on in the past. I would recommend sending them to a good cam grinder to get them checked etc.
Please see my other sales for more great Porsche parts including camshafts.
