That means at some point in that engines lifetime, the camshaft was replaced. For the 2mm method you want to use the specs for a '10' camshaft.
Hope that helps.

That is exactly what I needed to know. Thanks.
This also lends credence to my theory that the timing chain was indeed replaced (it would make sense that it would have been done at the same time as the camshaft).
In the previous owner's papers, I saw a very vague reference to timing chain replacement, but not actually a statement that it was done. From what I can see from above, the tensioner rail has no wear on it. Also, it's an IWIS chain.
That last bit of info doesn't necessarily mean the chain was replaced, but does mean that if it WAS replaced, they used a quality chain.
This car's an oddball, in that it it was cosmetically-trashed. But, I've found Mercedes part number stencils and stampings on everything I've touched on the car. My theory is that whatever work WAS done on the car was always done with quality parts. I think the car received better care mechanically than cosmetically.
