Copper in oil analysis ?

Aviation Consumer had a really good article on sources for all the
metals in an engine and their relationship to quantities found in engine
oil analysis. This appearred back in the 80's or 90's.
I have a single PDF page from Aviation Consumer's June 2006 article showing
a graph containing the metal in oil analysis and what produces it, as well
as what appears to be approximately normal results.
If the OP wants a copy of this, email me (remove the X from my attached
email address here) with a working address, and I will reply with this PDF.
