I have several NOS parts - many were bought as "lots", some were given to me by mechanics, etc. I have no idea where to look to find what model these go to, updated part numbers, etc. Many of these are 10yrs old or older, so I'm sure the PN's have changed or been updated. On the stuff I did find, I was surprised some of it actually would work on my own '91 300E.

Google searches (if I'm lucky) go to German sites, but still with little of no description or reference.

Any ideas?
