Richard, I have it here but only in German language. I can email it 
to you, if you want.

If available in English as well, I should have it somewhere, but I 
would have to look for it thoroughly. It might however be not 
available as the content mainly deals with the use of unleaded petrol 
on M116 and M117 with regards to Germany and the petrol grades that 
they used there at the time when leaded petrol was phased out in the 
1990s. It is only applicable to the non-catalyst engines that require 
lead due to unhardened valve shaft rings and the requirements for 
upgrading to the hardened versions and the changes for timing.
